Abstract

The invention discloses a composition for prevention and treatment of rice planthopper and a preparation method thereof, wherein the composition comprises the following raw materials in parts by weight: 15-25 parts of isazofos, 10-20 parts of solasodine, 120-140 parts of ethanol, 440-480 parts of water, and synergists propylparaben and magnesium sulfate with the total amount of 7-9 parts, wherein the weight part ratio of propylparaben to magnesium sulfate is (6-8) to 1. The composition provided by the invention can prevent and treat the rice planthopper, can be developed into pesticides for prevention and treatment of the rice planthopper, and has the prevention and treatment effect related to the weight part ratio of the synergist propylparaben to the synergist magnesium sulfate; and when the weight part ratio of propylparaben to magnesium sulfate is (6-8) to 1, the prevention and treatment effect is the best.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a composition for controlling rice planthopper and a preparation method thereof. Background technique [0002] Chlorazophos is an organophosphorus insecticide and nematicide with contact, stomach toxicity and systemic effects. Used on corn, cotton, rice, sugar beet, turf and vegetables to prevent pests such as cheetah, pumpkin twelve-star leaf beetle, Japanese beetle, nematodes, and planting ropes. [0003] Rice planthoppers belong to the family Planthoppers of the order Homoptera. There are mainly three types of brown planthopper, white-backed planthopper and brown planthopper that harm rice. The brown planthopper and the white-backed planthopper are the most harmful ones. The white-backed planthopper is the main species in the early rice stage, and the brown planthopper is the main species in the later stage; the brown planthopper is the main species in the middle and la...
