Description
Technical field
The present invention relates to a kind of propanil aqueous suspension agent compositions and preparation method thereof, belong to chemical insecticide technical field.
Background technique
Aqueous suspension agent refers to the preparation being dispersed in solid pesticide raw medicine with 5 μm of particles below in water, has grain
Diameter is small, active surface area is big, preparation penetration is strong, at low cost, drug effect is high and because of raw medicine sustained release, is not easy to send out
It is raw due to active compound content is excessively high in unit area and the phytotoxicity that generates.And due to there is no organic solvent in preparation, it is not easy to produce
The advantages that raw is inflammable, environmentally friendly.So aqueous suspension agent is for the modern higher and higher for environmental requirement
The product of trend of the times.
Propanil is the highly selective contact killing type herbicide of amides, is mainly used for rice seedling bed or live streaming field, prevents and kill off barnyard grass
Specific drug, it can also be used to prevent and kill off other a variety of grass family and broadleaf weed, such as Monochoria vaginalis, Chinese celery, herba digitariae, herba setariae viridis.Enemy
Barnyard grass hardly transporting in plant is only worked in medicament contact site.Its mechanism of action be it is various, not only break
The photosynthesis of bad plant, but also inhibit respiration and the phosphorylation of oxygen public affairs, interfering nucleic acid is synthesized with protein.From
And the physiological function of sensitive plant is made to be affected, and accelerate dehydration, blade gradually dried-up, it is last dead.Since propanil is in rice
Hydrolyzed enzyme resolves into rapidly innocuous substance in vivo, since degradation capability of the rice to propanil is 20 times bigger than barnyard grass, so to water
Rice safety.For propanil when illumination is strong, drug effect is obvious, but due to being all using propanil missible oil currently on the market, temperature is higher than 30
DEG C, when being also easy to produce phytotoxicity, but using propanil aqueous suspension agent, slowly due to the release of aqueous suspension agent raw medicine, so medicine will not be generated
Evil.
From the point of view of environmental protection, it is optimal mode that propanil, which is made into aqueous suspension agent,.The enemy of high-content is made simultaneously
Barnyard grass aqueous suspension agent can effectively save the costs such as packaging, transportation cost, and a kind of protection to environment.
Propanil aqueous suspension agent is easy to precipitate crystal during storage, so in the market without the commodity of propanil aqueous suspension agent.
