Peanut pest control

Peanut pest control

Disease control

Stem rot

If peanuts are infected with stem rot, the cotyledons will turn dark brown, gradually lose water and begin to dry rot. If not treated in time at the later stage, the black-brown diseased areas will rot, from leaves to stems, until the upper part of the plant dies.

One way to prevent and control peanut stem rot is to choose peanut seeds with better disease resistance or seeds that do not carry pathogens before planting. And the same crop cannot be planted repeatedly on the same plot of land. Another method is to use pesticide spraying after the disease occurs. Spraying 800 times diluted carbendazim two to three times, with an interval of about one week between each spraying, can effectively prevent the stem rot from getting worse.

Root rot

This usually occurs throughout the growth process of peanuts. The symptoms of the disease are that the leaves of the plant turn yellow from bottom to top, and then the leaves gradually fall off, the roots rot and die. Prevention and control methods: Mix seeds with carbendazim before planting, clean the land from diseases and insect pests, and spray 1000 times diluted carbendazim (50%) for treatment if the disease occurs after planting.

Pest Control

aphid

Aphids mainly attack the above-ground stems and leaves of peanuts, sucking the sap from the leaves. They also reproduce quickly and if not dealt with in time, they will endanger the growth of peanuts. Early detection and early prevention, spraying with omethoate spray can effectively eliminate aphids.

Grub

White grubs attack the underground peanut fruits. Not only will they eat the peanut shells and fruits, they will also bite off the peanut roots and cause the death of the plants. Severe white grub infestations can cause large areas of peanut seedlings to die and reduce yields. The first step to deal with white grubs is to take good care of the soil before sowing. Evenly spreading furadan or phorate and tilling it into the soil can effectively prevent and control white grubs. After sowing, you can mix chlorpyrifos with fine soil and bury it shallowly near the roots of peanuts to achieve effective control results.
