Method.
Background technology
Fosthiazate (fosthiazate) is organic phosphates nematicide, and main effect model is
The synthesis of suppression root-knot nematode acetylcholinesterase, can be used for preventing and treating all kinds of root-knot nematode.1. have
Have and tag and systemic action, kill root-knot nematode and mainly pass through two ways: nematicide contacts soil
In fosthiazate and dead；Be drawn in fosthiazate crop root kill invade crop root formed
The root-knot nematode of root nodule；2. quick-acting is good, and the lasting period is long, and fosthiazate is native after using latter 2 months
In earth, fosthiazate remains to reach root-knot nematode lethasl concentration, remains to reduce nematicide movable after 3 months；
3. the oriented upper transport properties of fosthiazate, strong to blade conduction by crop root, blade pass to flower
Lead weak, flower do not conduct to fruit；Can conduct to blade preventing and treating sucking pest such as
Aphid etc.；4. toxicity is relatively low, remains low, meets export of farm produce standard.
Fosthiazate is mainly based on cream at present, and Preparation Forms of Modern Pesticide is towards water baseization, ultra micro
Change, without efflorescence and control release aspect development, the i.e. formulations of pesticide with water as substrate, Qi Zhongshui
Emulsion be a kind of organic solvent can lack with even without, good drug efficacy, environmentally-friendly water-basedization
