Introduction to significant pests in paddy crop
Rice counts primarily in the list of staple foods and is also known as paddy. It is damaged very quickly by some insect pests. Farmers incur losses due to crop degradation, and it causes a hole in the pocket of rice farmers.
Here we’ll read about the preventive measures to save paddy crops using physical, mechanical, biological, and chemical prevention methods.
Some of the significant insects and pests in paddy crop which causes heavy damage:-
Plant hoppers, Stem borer, Rice Hispa beetle, Gall midge, Paddy leaf roller, Whiteflies, Rice bugs, Leaf miners, Aphids, Thrips, swarming caterpillars, and several more.
Let’s discuss a couple of them in detail.
Plant hoppers
There are two types of planthoppers that affect the paddy crop namely, Brown Plant Hopper (BPH) and White Backed Plant Hopper. Scientific names for these two are Nilaparvata lugens and Sogatella furcifera.
Let’s read about the symptoms of these:-
- Brown and white color nymphs are visible on the leaves.
- Crescent-shaped eggs can be visible in the midrib of the leaves.
- Leaves are turning into yellow and orange shades.

Physical or mechanical control
-
Protect the seedlings from direct exposure to insects by supplying enough water once a day such that only the tips of the seedlings are exposed.
-
To sweep the BPH, run a net over the seedling smoothly.
Biological and chemical prevention
- Release of spiders, mirid bugs, water striders, parasitoids, etc.; after that, avoid spraying the insecticides in the crop.
