Abstract

The invention discloses a pirimicarb and pymetrozine composition and a water dispersible granule thereof. The composition takes the pirimicarb and pymetrozine as active components; wherein, the mass ratio of the pymetrozine to the pirimicarb is 3:1-1:10. The water dispersible granule comprises the following components by weight percent: 5-50 pymetrozine, 5-60 pirimicarb, 0.5-30 dispersants, 1-10 wetting agents, 0.1-8 binders, 0.1-5 stabilizers, 1-15 disintegrants, 0-5 penetrants, a pH value regulator and balance of fillers; wherein, the pH value regulator regulates the pH value from 5 to 7. After the invention mixes the two insecticides with different mechanisms, the insecticidal effect is improved, the drug dosage is reduced, and the occurrence of resistance to drugs can be postponed and reduced; meanwhile, the number of times of pesticide application by farmers is reduced, the drug cost is lowered and the application is convenient. The composition of the invention is especially applied to preventing and curing Nilaparvata lugens (stal).

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a combination of pesticides and water-dispersible granules thereof. Background technique [0002] Pymetrozine chemical name: (E)-4,5-2hydro-6-methyl-4-(3-pyridylidenemethylamine)-1,2,4-triazin-3(2H)-one . Pymetrozine is a high-efficiency and low-toxic insecticide. It is safe for the environment, humans, livestock, natural enemies of pests and other beneficial organisms. It is not easy to produce resistance to pest control. It is an environmentally friendly insecticide. powder. [0003] Pirimicarb is a selective aphidicide with high efficiency, moderate toxicity and low residue. It does not harm bees and natural enemies at the recommended concentration. It is also very effective against Diptera pests. It can be used for fruit trees, cereals, berries, beans, cabbage , rape, lettuce, sugar beet, potato, flowers and some ornamental plants, it has quick effect and short durati...
