There are still 4 days left for the Dragon Boat Festival, which means that the time for planting is also coming. This period lasts until the end of July, which will be the worst season for rice and green bugs to harm crops.
The rice green bug is closely related to the lychee bug commonly known as the "stinky fart", but it is obviously much higher than the stink bug-infested crop.
First of all, it has the same color clothing as the green plant, which is relatively hidden and not easy to find; secondly, in addition to the longan and lychee that are dependent on the survival of the stinky fart, it also extends its vicious tentacles to crops such as rice, flowers, beans, citrus, mangoes, cotton, tobacco leaves and tea. It can be said that prevention and control governance is quite a headache.
Rice green bugs occur in 4 generations a year, overlapping generations, and overwintering in the fields, weed piles, tree holes, etc. It has super fertility and survival hunger tolerance, and it is more harmful to crops from the beginning of June --- the end of July.
Usually, rice green bugs should be artificially hunted in combination with thinning pruning. Medicaments can be used in areas where the damage is severe. When overwintering adults move into orchards and during the incubation period of large numbers of nymphs, it is advisable to use the drug 1---2 times for orchards with large insect population density. It can be used with 90% crystalline insect 800 times liquid, or 2.5% kung fu emulsion or 10% cypermethrin emulsion 2000 times liquid plus 80%, or 5% high efficiency cypermethrin emulsion 2000 --- 2500 times liquid.
At the same time as rational use of drugs, you can try to artificially breed or transfer the natural enemies of rice green bugs, and you can choose to breed 1---2 times with egg-jumping wasps or flat-bellied wasps.
