How to control pests in rice in summer

High temperature and humidity in summer create favorable conditions for the reproduction of insect pests, and it is a frequent season for the reproduction and damage of insect pests, so it is necessary to prevent the harm of pests to rice in this season. Here are several ways to prevent pests from rice:

Fumigation method

1. Aluminum phosphide fumigation was used to kill insects. If there is a large amount of rice with insects, the insecticidal treatment with special aluminum phosphide fumigation insecticides for grain can completely kill the pests.

2. Fumigation with phosphorus zinc and acetic acid. In the balcony or idle room (be careful to stay away from people and animals), put the rice bags of worms together in a sealed plastic bag, and then put a cup or bowl in the bag with 50 grams of vinegar; if the grain is not more than 500 kilograms, put one gram of zinc phosphide into the vinegar cup or bowl without stirring, seal the mouth of the bag immediately for fumigation. Sealed for 5-10 days, you can kill all the pests inside. Then dissipate the gas for 3 days, take out the vinegar water and the residue, and the rice can be eaten normally.

Exposure method

In summer, the cement drying table will be exposed to more than 50 ℃ in the sun, and then the insect-infested rice will be exposed on the platform. The pests and eggs will die quickly under the high temperature. However, after exposure to the sun, the broken rate of rice increased greatly, and the taste was not good.

Re-grinding and sieving method

All the pests on the surface of the rice grains and some of the pests and eggs inside the rice grains can be removed by re-grinding and screening the rice with rice grinders. It can effectively prevent the damage of pests to rice in two or three months. This is the safest and most environmentally friendly of the above methods.
