As an artificial intelligence language model, I don’t have first-hand experience in controlling sucking pest in urd crops. However, I can provide you with some information on this topic.
Urd crop, also known as black gram, is an important pulse crop grown in different parts of India. This crop has good export potential and is a source of income for many farmers. However, the crop is attacked by various pests, including sucking pests.
Sucking pests are insects that extract sap from the plant’s phloem tissues. They include aphids, whiteflies, thrips, and mites. Sucking pests cause damage to the crop by reducing the photosynthetic capacity of leaves, resulting in decreased yields and poor quality grains. The pests also transmit viruses, thereby increasing the chances of crop failure.
Controlling sucking pests in urd crops is necessary for increased crop production. Farmers can resort to two methods: chemical and non-chemical control.
Chemical control of sucking pests involves using synthetic or chemical insecticides. These insecticides include systemic and contact insecticides. Systemic insecticides are absorbed by the plant and transported to all its parts, while contact insecticides are sprayed directly on the pests.
While chemical control can offer fast results, it has its disadvantages. One disadvantage is that most pests tend to develop resistance to chemical insecticides over time. Also, chemical insecticides have negative impacts on the environment and non-target organisms, including beneficial insects.
Non-chemical control, on the other hand, is an environmentally friendly method that involves the use of natural enemies such as predators and parasites. Natural enemies include ladybirds, lacewings and parasitic wasps. These predators feed on the pests without causing significant damage to the crop.
In addition, farmers can opt for cultural control measures to control sucking pests. This involves practices such as crop rotation, intercropping and the use of resistant varieties.
Crop rotation can help disrupt the pest’s life cycle, while intercropping with non-host crops can help detract pests from the urd crop. Also, planting resistant varieties of urd crop can help minimize pest attack.
In conclusion, controlling sucking pests in urd crop is essential for a good yield. While chemical control may give fast results, it has negative impacts on the environment and other organisms. Non-chemical control and cultural practices offer a sustainable and environmentally friendly approach to pest control in urd crop production.
