Δdocument.getElementById( "ak_js" ).setAttribute( "value", ( new Date() ).getTime() ); Stem borers are very destructive maize pest; they are worm-like pests. Chemical control of cereal stem-borers - Volume 4 Issue 1-2. How do you look for Stalk borer infestations? Therefore we hypothesized that the farmers of the South West region: (1) also perceived stem borers as an important pest of maize; (2) they have their own indigenous methods of control; (3) they use chemical pesticides because they have no alternative, but would . ): Said Mir Khan and Muhammad Amjad: Abstract: The results of chemical control of maize stem borer Chilo partellus Swin. Results of the treatment further reveal that Furadan was found significantly more effective, followed by Ripcord and Tamaron which were found equally effective in the increase of number of cobs/plant. A REVIEW ON BIOLOGY AND MANAGEMENT OF MAIZE STEM BORER, Chilo partellus (Swinhoe, 1885) PRESENTER: Madan Subedi Msc.Ag. Annual Report of Atonomy Energy Agriculture Research Centres, New Dehli, pp: 121.Halimie, M.A., M.S. High dose of all the three insecticides gave better control of maize stem borer than medium and low doses. 2.2 Major Insect Pests of Regional Significance 1. Try and scout in a grid pattern to get an overall picture of the field. Smallholder farmers in South Africa can now access and grow new maize varieties with transgenic resistance to stem borers, the most damaging insect pest of maize. Make a channel of 2cm deep with a pointed stick in the middle of the space between the maize rows to plant the desmodium spp. The questionnaire sought to know: (a) the kind of indigenous methods and plant products used by farmers for maize stem borer control and their main constraints, as well as their knowledge on stem borer problems (b) if they use chemical/synthetic products to control pests, their names, the frequency of use and the constraints linked to their use . Found inside – Page 170Chemical control of stem borers Recommendation of some chemicals for the control of stem borers has been done since 2001. Verification of Ethiodemethrin 2.5% WDP insecticide against maize stem borer was conducted at Bako, ... Developments in maize stem borer control in East Africa, including the use of insecticide granules. In the Republic of Benin, the scelionid egg parasitoid Telenomus isis (Polaszek) is one of the most important control factors of the noctuid maize stem borer Sesamia calamistis. J. Agric. The pest can be controlled through a combination of cultural The most popular being the chemical method which relies heavily on the use of synthetic insecticide and fumigants. Once the farmer has determined that there is in fact a bad infestation of stalk borer in his maize crop (usually over 10% of plants) he will need to determine a plan of action. Prune the desmodium spp. Striga is a parasitic weed that impedes the growth of cereal crops like maize, rice, sorghum, millet, sugarcane, etc. This book is the third in a series of volumes on major tropical and sub-tropical crops. This leads to a great reduction in the yield and, at times, complete crop failure. seeds, you can use the root splits or cuttings. (2013) Validation of bio-control technology for suppression of Chilo partellus (Swinhoe) on Kharif maize in Punjab. Cobs weight (kg/plot): Data (Table 5) regarding cobs weight (kg/plot) reveal that the cobs weight of maize was significantly increased in all of the treated plots compared to the untreated plots at all of three tested doses of the insecticides. The stem borers initially damage by feeding on the leaf tissues, effective management of stem borers infesting maize, effective chemicals and their timing of application (early whorl stage) is significant as this pest is an internal feeder and control at later stage offers narrow scope for chemical control (Ravinder and Jawala, 2015) [11]. However, medium and low doses of insecticides were also found significantly better compared to the check. Make sure that you are always aware of what is going on in your field. This study shows how classical ecological principles, especially those relating to competition and population ecology, can be applied to growing two or more crops together and how the approach can improve agricultural yields. Maize stem borer (Chilo partellus Swinhoe) 2. We hope that the book will contribute to a more rational debate about the role GM crops can play in IPM for food and fiber production. Khan, Pakistan. At low and medium doses Furadan and Ripcord were found more effective than Tamaron while at high dose all of the tested insecticides were found significantly different from each others in the reduction of pest population and in the increase of grain weight/plot. Eggs hatch into caterpillars, which move into the growing points, where they start to feed. Wear gloves, a face mask and protective glasses when dealing with any chemical. It is a primary component of animal feeds; it is the best source of energy for farm animals. 1998/99 growing season for control of stem borers. Ahmad (1987) concluded that the application of Furadan, Temic and -Paden to "sunehri" maize had influence on the physiomorphic character of the crop. The edited book Pesticides - Toxic Aspects contains an overview of attractive researchers of pesticide toxicology that covers the hazardous effects of common chemical pesticide agents employed every day in our agricultural practices. Modern agriculture has made huge advances in cultivar development. All the three tested doses were found significantly different from each other in the control of pest and in the increase of stalk weight of maize. problems among which Lepidoptera insect pest especially maize stem borer Chilo partellus are the most destructive ones (Singh and Sharma, 2009) [35]. This method reduces pollution and limits harmful . and Control Of Stalk Borers In Maize Crops Introduction . Striga affects a cereal crop by attaching itself to the roots of the cereal crop like maize; it competes with the maize plant for nutrients. Non- BT maize has to be planted with BT maize to prevent the development of insect resistance. Furadan and Ripcord were found non-significantly different from each other, while Tamaron was significantly different from these two insecticides. It involves intercropping maize with desmodium spp plant, surrounding the plot with Napier grass (Elephant grass). Sarhad J. integrated pest management practices to reduce crop losses caused by diseases and insect pests of maize. The desmodium spp plant by nature produces a pungent smell that repels the adult stem borer; also, it secretes a chemical that prevents Striga from attaching to the roots of the maize plants. Kisan variety of maize was sown in plots (3 × 2 m2) with tar waiter condition. It is non-toxic as it does not involve the use of chemicals; it is 100% organic. Chemical control by means of insecticidal sprays is effective against stem borer larvae when . Therefore, termites should be controlled in maize apart from treatment for shoot fly and borer. The pink stem borer (PSB), Sesamia inferens Walker is one of the major insect pests in the winter maize which results 25.7-78.9 percent yield losses 1.The larvae feed inside the leaf sheath in groups and subsequently bore into the central shoot resulting in the formation of dead hearts.The larvae form circular-shaped tunnels inside the stem and exit holes on the stem surface. Found inside – Page viiIn Kenya , stem borers inflict maize yield losses estimated to be on average 13.5 % valued at KES 5.6 billion ( US ... Using chemical control ( Bulldock ) on approximately 70,000 ha of maize grown in the Coast Province would cost about ... Adult stem-borer moth captures consisted of 76.4% C.partellus and 23.6% C.orichalcociliellus.The highest and lowest numbers of moths were captured in the maize monocrop plots and leucaena monocrop plots, respectively ().The comparisons indicate that the captures were significantly higher in the maize monocrop than in the intercropped plots, and captures were significantly fewer in the leucaena . The most prominent sign to look for is holes on the leaves in perfect formation. But many do not go for . Weight of stalk (kg/plot): Results (Table 4) show that the stalk weight per plot of maize was significantly more in all of the treated plots compared to untreated plots. Cultural Control. All of these tested insecticides and their doses were found significantly different from each other at 5% level of probability. Agric., 8: 205-208. The number of cobs/plant obtained in the control plots were significantly less compared to the treated plots. Copyright 2021 | Designed and Maintained by Thoughtcorp, Grain SA & SA Grain Website Advertising Rates, Prevention and control of Stalk borer in maize. On older plants, they bore through the upper nodes and feed toward the base. Its by-products are essential to humans and animals, especially in animal production. The best method to control Striga and Stem borer is the Push-pull system. • Cereal borer complex (Rice, maize and wheat) • Coffee white stem borer • Sugarcane pests - Plassey borer management - Early shoot borer management - Seed bed beetle, Heteronychus sp. Stem borer damage the stalks while armyworms damage the leaves. For Napier grass (Elephant grass), it attracts the adult stem borers; the adult stem borers lay their eggs on the Napier grass (Elephant grass) instead of the maize plants. This handbook, designed to facilitate the identification of common insects affecting maize, contains descriptions and color photographs of pests of the seed, root, and seedling, pests of the foliage and tassel; pests of the stem, ear, and ... Khan (1983), Marwaha et al. The stem borer larvae bore at the base of the plants during the vegetative stage. Maize stem borer (Chilo partellus) 1. Designed for reviewers of research manuscripts and proposals in the social and behavioral sciences, and beyond, this title includes chapters that address traditional and emerging quantitative methods of data analysis. Moths fly at night and lay eggs on maize plants between the leaf sheath and the stem on the youngest fully unfolded leaf. There are several stem-borer species recorded on important cereals such as rice, maize and sorghum as well as on grain legumes like cowpea. The data reveal that Furadan was significantly most effective in the control of maize stern borer and in the increase of maize stalk weight per plot followed by Ripcord and Tamaron at the three tested doses. plant at 6 weeks so that they do not outgrow your maize plant. The first Bt maize resistant B. fusca in South Africa was recorded during the 2006/07 growing season and resistance has since spread to many areas in the country. We need to learn how to defend our crops against these enemies to the best of our abilities. Before the farmer applies the chemical, he should be sure of the exact purpose of the chemical as not all poisons are the same. Also, using tolerant or improved seeds seems better but it is hard to come by and very expensive. Found inside – Page 339All parts of maize plant, i.e. root, stem, leaf, grain (milky and ripe) and seeds are attacked and damaged by these ... Various methods of pest control, namely mechanical, cultural, biological and chemical, have been developed to check ... 2. Armyworms are prolific and sensitive to favorable conditions. Anwar and All living organisms have enemies, even the maize plant. The grey moth is the male and the white moth is the female. Neonate B. fusca and C. partellus larvae feed The caterpillars bore into the stem of maize, feed on the internal tissues and cause the plant to wither and die. the data that chemical control of borers' and shoot fly would have no effect on termites and vice versa. They germinate mainly when cereal crop is planted. This book contains 20 chapters, which are divided into 5 sections. Chemical Control Simple neem products are reported to be effective for control of stem borers. Stay updated with our posts by subscribing to our posts via email and get instant notifications on new posts. This method has limited effectiveness once the larvae bore into the stem. Focus on The experiment was laid down in randomized complete block design with split plot arrangement. Low doses of all tested-insecticides were found non-significantly different from each other and significantly different from the check in the control of maize stern borer. Materials and Methods It is non-toxic as it does not involve the use of chemicals; it is 100% organic. we discuss how we control of maize stem borer. For effective management of stem borers infesting maize, effective chemicals and their timing of application (early whorl stage) is significant as this pest is internal feeder and control at different stage offers narrow scope for chemical control [16]. Almost 75% damage of the crop occurs due to attack of maize stem borer. It attacks all parts of the maize plant except roots (Anonymous, 1986). INTRODUCTION • One of the most severe insect pests of maize in Nepal (Neupane, 1986) • Damage results dead . The action threshold for chemical control of stem borers in maize is when 10% of plants (mixed infestations of B. fusca and C. partellus) in a field show visible symptoms of whorl damage (Van den Berg et al., 2015). Farmers have come up with their own ways of controlling the stem borer, like adding mixtures of sand and ash to the soil and applying pepper and neem, but this has not been effective compared to chemical control. Lepidopterous maize stem borers are a major threat to increase maize production. The data show that number of cobs per plant were significantly increased in all of the tested insecticides at low and medium doses compared to the check. Almost 75% damage of the crop occurs due to attack of maize stem borer. 10. The results show that Furadan was most effective in the control of the pest and in the increase of average cobs weight, followed by Ripcord and Tamaron at low dose. I think it may help all of you. The larva or caterpillar stage in the life causes major damage to maize and sorghum crops throughout the region and in particular South Africa. This can prove challenging sometimes as nature likes to throw a curve ball occasionally. All three of these maize stem borers are successfully controlled by Bt maize. Biological Control Many natural enemies of the African maize stalk borer have been reported two of the most abundant natural enemies or the larval parasitoids cotesia sesamiac and bracon sesamiac. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging ... All of the three insecticides were found non-significantly different from each other and were found significa-ntly different from the check at 5% level of probability. Prune the desmodium spp. In extremely severe cases, 100% yield losses were recorded in individual farming systems in spite of chemical control measures. Lepidopteran stemborers are highly injurious to maize, sorghum, and millet in sub-Saharan Africa. In case you cannot find the desmodium spp. One can walk through the field at night and identify weather there are small grey and white moths present. Some maize cultivars have now been genetically modified to withstand infestations of Stalk borer. This system is the most effective in controlling Striga and Stem borer. High dose of the insecticides was found significantly most effective, followed by medium and low doses. Photo: B.Wawa/CIMMYT. The means regarding insecticides and their doses were separated by LSD test. Jotwani, M. G. (1983) Chemical control of cereal stem-borers. This volume is a diverse collection of self-contained articles on molecular-level research using Lepidoptera. MATERIALS AND M ETHODS Field experiments were conducted at Maize Research Centre, ARI, Rajendranagar, Hyderabad for two seasons during Kharif 2009 and Rabi 2009-2010 in a randomized block design to assess the bio-efficacy of Thiamethoxam 30 FS on . In trials, the number of stem borer eggs, and plant damage caused by stem borer feeding, have been found to be significantly higher in monocropped maize plots than in push-pull fields. Chemical control is an important tool for stem borer control in maize. Response of different timings of carbofuran (Furadan 3G) on the maize borer incidence and yield of the crop. tested for host plant resistance to the spotted stem borer, and several highly resistant or toler-ant varieties were identified and documented for most maize production zones []. 2. A gener-ally accepted estimate of annual losses during the early part of the 20th century was 10% of the national crop (Mally, 1920). GM maize seed cost considerably more than standard non-GM seed. These results further reveal that Furadan was ranked first in the reduction of dead hearts to 5.52%, followed by Tamaron and Ripcord which reduced the dead hearts to 5.90 and 6.60% respectively, compared to 8.82% in the control plots. Napier grass is an effective catch crop for controlling stem borers. How to control maize stem borer ,chemical control of maize stem borer, maize cultivation in Punjab. January 2016. Maize is the most widely produced crop in South Africa, grown extensively in the Free state, Mpumalanga, and the North West as well as most other provinces but in smaller expanses. The economic importance of the stem borer in Africa results in their severe damage that affect directly cereal yield factors such as the density of fertile tillers and the number of effective panicles. The push-pull system is a combined method of controlling both Striga and Stem borer simultaneously. These two factors are great threats to crop production. As dreadful as these pests are, they can be controlled but controlling them is more technical. Napier grass also attracts stem borer predators. According to, Chinwada and Overholt, (2001), most smallholders and communal farmers do not control the maize Stem borer. Knowledge of common maize crop pests can help smallholder farmers in early identification and control. ; Striga is a hardy weed; its seeds can reside in the soil for a long period, say 15 years. Ensure that the first row of the maize plant is about 1m away from the Napier grass (Elephant grass). Thiamethoxam 30 FS as seed treatment against stem borers and its phytotoxic effect on maize plant. Thank you, […] and stem borers are the two virulent pests of plantain and banana; they attack the sucker at the root […]. When the eggs hatch, the Napier grass (Elephant grass) produces sticky glue that traps and kills the young stem borer. dead heart, which ultimately reduces maize yield. Enhancing maize productivity on the field, therefore requires the control of stem borer activities. Annals of Applied Biology 84: 111-114.
