Control of insects in arhar crop
Arhar or pigeon pea is an important pulse crop in India. It is a rich source of protein and other essential nutrients. However, like any other crop, arhar is susceptible to various insect pests that can cause serious damage to the crop resulting in reduced yield and poor quality produce. Therefore, it is important for farmers to take timely and appropriate measures to control insects in arhar crop.
Here are some effective ways to control insects in arhar crop:
1. Use resistant varieties
Planting resistant varieties of arhar can be an effective way to control insect pests. Some of the commonly grown resistant varieties of arhar are ICPL 87, BDN 2-7, and JKM1. These varieties have been developed through plant breeding to resist insect pests such as pod borer and pod fly.
2. Monitor insect population
Monitoring insect population in arhar crop is crucial for effective pest management. Farmers should regularly inspect their crops for signs of insect infestation. Visual symptoms such as wilting, yellowing, and stunted growth can be indicative of insect damage. Farmers can also use pheromone traps to monitor the population of pod borers and pod flies.
3. Use biopesticides
Biopesticides are natural substances derived from plants, animals, or microorganisms that can control insect pests. They are safe for the environment and do not harm beneficial insects. Some of the commonly used biopesticides in arhar crop are neem oil, garlic extract, and tobacco extract. These biopesticides are effective against pod borers, pod flies, and other insects.
4. Use chemical pesticides
Chemical pesticides can be used to control insects in arhar crop. However, farmers should use them judiciously as they can have adverse effects on the environment and human health. Farmers should follow the instructions on the label carefully and apply the pesticide at the recommended dose and time. Some of the commonly used pesticides in arhar crop are pyrethroids, carbamates, and organophosphates.
5. Crop rotation
Crop rotation is a cultural practice that can help control insect pests in arhar crop. Farmers should avoid growing arhar continuously in the same field as it can lead to the buildup of insect pests. Instead, they should rotate arhar with other crops such as maize, sorghum, or vegetables. This can help break the life cycle of the pest and reduce infestation in subsequent crops.
In conclusion, insect pests can cause serious damage to arhar crop resulting in reduced yield and poor quality produce. To control insect pests, farmers should use resistant varieties, monitor insect population, use biopesticides, use chemical pesticides judiciously, and practice crop rotation. Taking timely and appropriate measures to control insect pests can help farmers achieve higher yields and better quality produce.
