What Pesticides Work Well to Control Corn Soil Pests

Corn is a common crop in our country, grown by almost every household, and during corn cultivation, various diseases and pests often appear. So what pesticides should be used to control corn soil pests?

1. What pesticides should be used to control corn soil pests?

Corn soil pests can be controlled with pesticides such as trichlorfon, phoxim, deltamethrin, methamidophos, deltamethrin, and fenvalerate. Generally, for 1st and 2nd instar larvae, a 20% fenvalerate 3000-fold solution, 2.5% deltamethrin, or a 50% phoxim 800-fold solution can be used for spray control. For older larvae, use 100 grams of 50% phoxim per mu plus 30 kg of chopped vegetable leaves, mix well and broadcast to poison them.

2. What are the corn soil pests?

1. Cutworms

Cutworm larvae before the 3rd instar mostly move on the soil surface or on plants, feeding day and night on leaves, heart leaves, tender tips, and buds, with a relatively small amount of feeding. After the 3rd instar, they scatter into the soil and hide there during the day; their nighttime activity causes damage to plants, often biting off corn seedlings above ground, leading to seedling shortages and broken rows.

2. Mole crickets

They all live underground, eating newly sown seeds and biting corn roots, causing great harm to corn seedlings, and are very important soil pests. They usually live underground and are active underground at night and in the morning.

3. White grubs

They are the larvae of beetles and like to eat newly sown seeds, roots, tubers, and seedlings. They are a worldwide soil pest, occurring in soft, moist soil, and are most common in irrigated land.
