Control of aphids/sundi in wheat crop

Sure, here is an article on the control of aphids/sundi in wheat crops:

Wheat crops are susceptible to various pests and diseases, and among them, aphids and sundi are the most common. Both of these pests can cause significant damage to the wheat crop, resulting in reduced yields and quality. Hence, it’s crucial to control their populations to minimize their impact on the crop. In this article, we’ll discuss the effective methods of controlling aphids and sundi in wheat crops.

Identification of Aphids and Sundi

Aphids and sundi are small, soft-bodied insects that feed on wheat plants. Aphids are usually green, yellow, or black in color and measure about 1-2 mm in length. Sundi, on the other hand, is a small, dark-brown pest with a slightly elongated body. They are usually found on the stems, leaves, and other parts of wheat plants.

Their feeding activity causes yellowing or wilting of leaves, stunted growth, and in severe cases, the death of the plant. Moreover, aphids secrete a sticky substance called honeydew that attracts other pests and promotes fungal growth, resulting in the formation of sooty mold on the wheat plant.

Effective Control Measures for Aphids and Sundi

1. Cultural Methods

One of the best ways to prevent pest infestations is to adopt cultural practices that create an unfavorable environment for their growth and reproduction. Some of the cultural methods to control aphids and sundi in wheat crop include crop rotation, timely planting, and proper field sanitation.

Crop rotation: Growing different crops in rotation helps to break the pest’s lifecycle by interrupting their breeding cycle.

Timely planting: Early planting helps the wheat crop grow and mature quickly, thereby preventing pest infestations.

Proper field sanitation: Removing weed hosts and infected plants from the field prevents the spread of pest infestations.

2. Chemical Control

Chemical control involves the use of insecticides to control pest populations. Spraying insecticides at the appropriate time helps to reduce pest populations and prevent further crop damage. However, it’s essential to choose an appropriate insecticide, dosage, and application method to minimize the risks associated with chemical use.

It’s crucial to note that excessive use of insecticides can lead to pesticide resistance in pests, environmental pollution, and adverse effects on beneficial insects.

3. Biological Control

Biological control involves the use of natural enemies to control pest populations in wheat crops. Some of the biological control agents for aphids and sundi include ladybugs, lacewings, and parasites such as parasitic wasps. Introducing these natural enemies into the field helps to reduce pest populations and maintain a balanced ecosystem.


Effective control of aphids and sundi in wheat crops requires a combination of cultural, chemical, and biological methods. Timely identification of pest infestations and appropriate control measures can help to prevent further crop damage and losses. Hence, farmers and other stakeholders should take proactive measures to manage pest infestations and optimize wheat crop yields and quality.
