Abstract
The invention belongs to technical field of pesticide preparations, more particularly to a kind of clethodim EC and preparation method thereof, clethodim EC, include the raw material of following mass fraction：Clethodim, 12~24%；Organic solvent, 61~73%；Emulsifying agent, 5~15%；Stabilizer, 5~10%；The stabilizer is N, the diaminopropanes of two salicylidenes of N ' 1,3；Using N, the diaminopropanes of two salicylidenes of N ' 1,3 interacts, resolution ratio is high after solving the problems, such as clethodim storage as stabilizer with other components；Property is stable, is not in layering and precipitation devitrification problem in storage process, can be widely applied to herbicide.
Description
Technical field
The invention belongs to technical field of pesticide preparations, more particularly to a kind of clethodim EC and preparation method thereof.
Background technology
The production of herbicide still just persistently keeps strong growing trend in China in recent years, and increasing degree is considerably beyond other classes
Type agricultural chemicals, the proportion of herbicide is also close to 50% in agricultural chemicals, and chemical weed control area is with the speed increases of annual 30000000 mu times, mesh
It is preceding that up to 600,000,000 mu times, herbicide market will expand into more than the 70% of national pesticide market in several years from now on,
Clethodim category cyclohexenone analog inner sucting conduction type cauline leaf process agent, there is very strong lethal effect to grassy weed.
It is a kind of new dry land herbicide after seedling, there is excellent selectivity；It is notable to grassy weed preventive effect, can be by standing grain after dispenser
Undergraduate course weeds cauline leaf absorbs rapidly and conducted the activity for stem apex and separate living tissue, suppressing separate living tissue, destroys cell division, applies
Plant moves back green necrosis, the withered death of subsequent leaf in 1-3 weeks after medicine.Clethodim use range is wide, can be applicable to rape, soybean, flower
The various broad leaf crop fields such as raw, it is highly safe to broad leaf crop；Broad weed-killing spectrum, it is each that such as wild oat, lady's-grass, annual bluegrass can be prevented and treated
Kind annual and grassy weed for many years；Low temperature resistant, more than 2 DEG C can normally play drug effect；Absorb rapidly, 1 hour after dispenser
Absorbed by weeds.Crop field residual is short, and acute toxicity is low, and security is good；Broad leaf crop is compared in larger dosage range
Safety, makes the yield increasing effect of soybean obvious；Clethodim spraying treatment, Activity determination show that its soil longevity of residure is shorter.To rear stubble
Crop is without influence；Overcome the drug injury problems such as drift；Its activity is higher, and dosage is less, is advantageous to overcome anti-caused by use
Sex chromosome mosaicism.
But clethodim degraded is fast, under the conditions of 50 DEG C, 0.7 month active compound half-life period；Clethodim EC in the market, storage
It is high to deposit resolution ratio in the phase, about 11% -20% or so, heating storage decomposition is more serious, has a strong impact on the performance of drug effect.
