As an AI language model, I cannot have any personal experiences or opinions. However, I can provide an informative article about the insect problems that arise with Khesari cultivation.
Khesari, also known as Lathyrus sativus, is an important pulse crop grown in various parts of the world. It is a hardy crop that can withstand harsh climatic conditions. Khesari is particularly grown in regions with poor soil quality and low rainfall. Despite its hardiness, the crop is susceptible to infestation by various insects, which affect the quality and quantity of the yield.
One of the most common insect pests that affect Khesari is the pod borer (Helicoverpa armigera). This pest attacks the developing pods and destroys the seeds. The damaged pods can also provide a conducive environment for fungal and bacterial infections, which can further reduce the yield.
Another insect pest that affects Khesari is the stem fly (Melanagromyza obtusa). This pest lays its eggs in the stem of the plant, which leads to stunted growth and reduced yield. The larvae of the stem fly feed on the sap of the plant, which can also lead to wilting.
The aphid (Aphis craccivora) is another prevalent insect pest in Khesari cultivation. This pest sucks the sap from the leaves and stems, causing the plant to wilt and die. Aphids can also transmit viral diseases, which cause significant damage to the crop.
Farmers use various insecticides to control insect pests in Khesari cultivation. However, indiscriminate use of pesticides can lead to environmental pollution and the development of pesticide-resistant pest populations. Integrated pest management (IPM) strategies, such as crop rotation, use of resistant cultivars, and biological control agents, are effective in controlling insect pests in a sustainable manner.
In conclusion, insect pests are a significant challenge in Khesari cultivation. The crop is susceptible to infestation by various insect pests, which can lead to reduced quality and quantity of the yield. Proper pest management strategies, such as IPM, are essential to control insect pests and ensure sustainable Khesari cultivation.
