Control of Army Worm and Pink Stem Borer in Wheat Crop
Army worm and pink stem borer are the most destructive pests in wheat crop, causing severe damage to the yield. These pests are prevalent in most wheat-growing regions and can result in a significant loss of farmers’ income. Therefore, controlling these pests is essential for achieving a successful wheat harvest. Here are some measures that can help in controlling army worm and pink stem borer in wheat crop.
Cultural Methods
Cultural methods are the most effective and environmentally friendly approach to control pests in wheat crops. Farmers should consider crop rotation, intercropping, and maintaining the field’s hygiene to reduce the infestation of army worms and pink stem borers. Crop rotation is particularly effective in reducing pest populations, as they may not be able to feed on hosts other than wheat. Intercropping of wheat with leguminous crops like beans and peas also helps to deter army worms and pink stem borers from attacking wheat.
Biological Control
Biological control involves the use of natural enemies such as parasites, predators, and pathogens to control pests. Parasitic wasps are natural enemies of army worms, and farmers can release them in the field to control the population. The use of Bacillus thuringiensis (Bt) is also an effective biological control method against both pests, which can be applied through spraying. Bt is a naturally occurring soil bacterium that produces proteins that are toxic to army worms and pink stem borers, causing them to die.
Chemical Control
Chemical control involves the use of synthetic pesticides to control pest populations. The use of pesticide should be a last resort since it can have harmful effects on non-target organisms and the environment. Farmers should apply the pesticide according to the manufacturer’s recommendations and avoid spraying during flowering when bees are active. Also, farmers must adhere to the pre-harvest intervals, to allow for the destruction of the active ingredients in the pesticides.
In conclusion, controlling army worms and pink stem borers in wheat crops is essential for achieving a successful and healthy harvest. Cultural and biological control measures are the most effective and environmentally friendly approach, while the use of pesticides should be the last resort.
