Certainly, here’s an article on Whitefly/Sundi Control in Cotton:
Whitefly and Sundi are two major pests that feed on cotton plants. A high infestation of these pests can cause a significant reduction in crop yield. The control of these pests in cotton is, therefore, essential to increase the productivity of the crop.
Whitefly:
Whitefly infestations are commonly seen in cotton crops. They cause damage by sucking the sap from the leaves of the plants. This sap sucking also results in the wilting of leaves and the discoloration of the plant. Additionally, the whitefly secretes a sticky substance that attracts mold. Large whitefly populations can also lead to the spread of plant viruses.
Control measures:
1. Cultural control:
Practices such as crop rotation, removing and destroying plant debris and weeds, and maintaining a clean field environment can help reduce whitefly populations.
2. Chemical control:
The use of insecticides is also an effective way to control whitefly populations. However, the selection of insecticides should be based on proper scouting and identification of the insect population.
3. Biological control:
Predatory insects such as ladybugs, lacewings, and parasitic wasps are natural enemies of the whitefly. Release of these predators into the field can help control whitefly populations without the use of insecticides.
Sundi:
Sundi is another cotton pest that can cause widespread crop damage. They primarily feed on the plant’s reproductive structures, including young bolls and flower buds. This feeding results in distorted and misshapen bolls, affecting the overall yield and quality of the cotton crop.
Control measures:
1. Cultural control:
Proper tillage practices, close monitoring of boll maturity, and handpicking/destroying affected bolls can help reduce Sundi populations.
2. Chemical control:
Insecticides can be an effective method of controlling Sundi populations. However, similar to whitefly control, the selection of insecticides should be based on proper scouting and identification of the insect population.
3. Biological control:
Predatory insects such as ladybugs, praying mantis, and spiders are natural enemies of Sundi. Release of these predators can help reduce Sundi populations.
In conclusion, whitefly and Sundi control measures should be implemented to increase cotton crop productivity. Cultural and biological control methods should be used initially, while using insecticides should be the last resort. Proper scouting, identification, and selection of control methods based on the insect population can help ensure the effective management of these pests.
