Background technology
In agricultural production, because the pathogen entrained by seeds self, the pathogen in soil, seedling stage are airborne
Pathogen, insect pest etc. often result in diseases and pests of agronomic crop, and serious even No kernels or seeds are gathered, as in a year of scarcity, becomes a major limitation of agricultural production
The factor.Seed chemicals treatment is preventing and treating subterranean pest-insect and crops soil biography, the method for seed-borne disease economical and convenient in agricultural production
One of.Seed coating technology is a kind of very universal seed growing up in traditional seed soaking or seed dressing technical foundation
Process new technique.
The seed coat agent that Spread in China uses at present is various in style, but mostly there are some problems.Such as Likeming Gel, suitable happy when,
The single functions, only prophylaxis effect such as seed dressing pair, and use technical sophistication, dangerous to crop；Trophophase aphid can effectively be prevented and treated
The non-target life to Apiss etc. of the product of the suckings pest such as worm, the plant hopper such as anabasine insecticide such as imidacloprid, Diacloden
Thing toxicity is larger.
Therefore, in order to adapt to the actual requirement of agricultural production, need continual exploitation a kind of relatively low to non-target organism toxicity, right
The sucking pest prevention effect such as trophophase aphid, plant hopper is good, and can prevent and treat the product of multiple diseases.My company grinds
The personnel of sending out, after many experiments, propose a kind of new Fungicidal insecticidal composition suspended seed coating agent prescription, it mainly has finally
Effect composition be pymetrozine, prothioconazoles, both have the good compatibility, accomplish disease pest double play, can solve well more than
The problem running in actual production.
