Abstract

The invention belongs to the field of weed killer, in particular to a pyrithiobac-sodium containing soluble powder, soluble granules and soluble tablets. The invention aims at providing a pyrithiobac-sodium containing pesticide new formulation as well as improving the utilization rate of active ingredients and enhancing environmental compatibility by improving the formulation. The technical scheme thereof includes that a pyrithiobac-sodium containing soluble powder, soluble granules or soluble tablets comprises the components such as pyrithiobac-sodium crude drug, wetting agent, dispersing agent and a carrier, wherein the soluble tablets also comprise adhesive, lubricating agent and disintegrating agent. The invention has the beneficial effects: firstly, product is completely dissolved in water when in use, thus spraying is more uniform; secondly, the pyrithiobac-sodium containing soluble powder, soluble granules and soluble tablets are solid, thus being convenient for production and transportation and reducing production cost.

Description

technical field [0001] The invention belongs to the field of pesticide herbicides, in particular to a soluble powder, a soluble granule and a soluble tablet containing pyrimiazide. Background technique [0002] Today's world puts forward strict requirements on the safety of pesticides, which makes ordinary enterprises unable to bear the funds and time for new pesticide research and development. service life. At present, the main direction of dosage form processing is to manufacture preparations with the following functions: reduce toxicity, improve safety; reduce pollution; reduce phytotoxicity to crops; be safer for users; easy to use, save labor; save energy and reduce prices; Improve bioavailability; develop in the direction of water-based. [0003] Pyrimicarb-sulfen, also known as pyrimthiocarb-in; chemical name: sodium 2-chloro-6-(4,6-dimethoxypyrimidin-2-ylthio)benzoate, CAS number: 123343-16-8 Molecular formula: C13H10C1N2NaO4S molecular weight 348.7373, structural...
