Rice pest control: how to control rice locusts?

How to control rice locusts? What are the hazards of rice locusts? Please introduce the harm of rice locusts: Rice locusts, commonly known as "grasshoppers", are one of the important pests in the middle and later stages of rice. both adults and nymphs cause damage, mainly to rice, but also to corn, sorghum, beans and other crops. In the milky stage of rice, white panicles are often caused by biting off the ear neck and branchlets, resulting in a serious reduction in rice yield. The control methods of rice locusts are as follows: 1. 21% EC (synergistic cyanide? Horse EC) 1500-2000 times liquid spray. 2. Use 4.5% cypermethrin EC 1500 times liquid spray. 3. Using 21% Kill 2000 EC 1500 Mel 2000 times liquid spray. 4. The biological pesticides used to control locusts are microsporidium locusts, Metarhizium anisopliae and azadirachtin. Locust microsporidia are locust-specific, single-celled protozoa. Locusts can cause microsporidiosis after eating food with microsporidia. Metarhizium anisopliae is the pathogenic fungus of locusts. After the locusts come into contact with the fungus, the fungus can penetrate the locust's skin (body wall) and enter the locust's body to reproduce, either produce toxins, or the hyphae grow all over the locust's body to kill the locust. Azadirachtin is a substance extracted from a tree called neem and is a botanical insecticide. Click to get more rice planting techniques click to get more food crop planting techniques
