Description
Technical field
The present invention relates to agriculture chemical compounding field, particularly relates to a kind of active ingredient with prothioconazoles, imidacloprid and Diacloden
For the seed treatment composition of active ingredient and its application.
Background technology
Seed treatment is a kind of agricultural chemicals for being used for the surface of the seed processing, and active ingredient is mainly insecticide or bactericide,
With the preventing and treating crops seedling stage disease pest plague of rats, improve the effect such as seedling percent.Compared with conventional use of cauline leaf process agricultural chemicals, kind
Subprocessing agent is reducing applications of pesticide amount and application times, reduces environmental pollution, and reduces field operational sequence, saving of labor, abridged edition, increasing
Effect etc. has a clear superiority.
The seed processing technology that China vigorously advocates and promoted in recent years, mainly by insecticide, bactericide, composite fertilizer
The compositions such as material, trace element and plant growth regulator are compounded, and are formed the seed treatment product of difference in functionality, are disappeared with reaching
Except and disease and pest control, breaking dormancy, nutrition is provided, regulation is grown, adjusts moisture around seed, oxygen, temperature etc.
Subenvironment and regulation shape of the seed, the purpose of size, realize that breeding standardizes.
At present, the demand of the annual crop seeds in China is about 7,000,000 tons, wherein about 3,500,000 tons of commodity seed amount, is done
Cotton seeds account for 10% or so, it is seen that the market demand of breeding coating agent is huge, and prospect is very wide.
It is the New-type wide-spectrum triazolinthione series bactericidal agent of Beyer Co., Ltd's exploitation in 2004 shown in prothioconazoles such as formula (I).With
Triazole bactericidal agent is compared, and has the bactericidal activity of more wide spectrum, most important application crop is cereal, rape and peanut.Third
Sulphur bacterium azoles almost has good preventive effect to all diseases of wheat class, such as powdery mildew, banded sclerotial blight, droop, leaf spot, rust, bacterium
Core disease, net blotch, moire disease etc., particularly have special activity to banded sclerotial blight and spot blight.The mechanism of action of prothioconazoles
It is to suppress the demethylation effect in fungi on the precursor-lanosterol or 2,4- methylene lanostenol 14 of sterol,
That is demethylation inhibitors (DMIs).Not only there is good systemic activity, excellent protection, treatment, the activity eradicated, and
Lasting period is grown.Because single dose is long-term use of, treatment target has produced the very strong resistance to the action of a drug, has caused drug effect to reduce, and the lasting period shortens.
Imidacloprid (Imidacloprid) as shown in formula (II), also known as 1- (6- chloro-3-pyridyls ylmethyl) -4,5- dihydros -
N- Nitroimidazoline -2- bases amine, imidacloprid, deinsectization essence, net, the molecular formula C that flutters lice aphid, aphid lice9H10ClN5O2, belong to nitro
Methylene base class systemic fungicide, it is the acting body of nicotinic acetylcholine esterase acceptor, interference pest movements nervous system makes chemistry
Signal transmits failure, no interactions resistance problem.For preventing and treating sucking pest and its resistant strain.Imidacloprid is a new generation
