Abstract
The present invention relates to pesticide and a processing field thereof. The present invention provides a binary compounding composition of a kind of myclobutanil and other kinds of bactericide. The use of the mixing bactericide can obviously delay the generation of the drug resistance of pathogenic bacteria to the myclobutanil, and the present invention can be widely used for the prevention and the cure of fungal diseases on crops.
Description
The present invention relates to agricultural chemicals and manufacture field thereof, specifically the present invention relates to contain the bactericidal composition and the manufacture method thereof of nitrile bacterium azoles.
Crop is subjected to the dip-dye of various diseases, particularly fungal disease easily in growth and development process, it is of a great variety, endanger the most serious, as wheat rust, the scab of apple, pears etc., the outburst of these diseases has in recent years caused destructive strike to the production of these crops.For a long time, the control of crop pest is mainly relied on and chemical control, i.e. the application of bactericide, but the long-term use of bactericide have caused the pesticide resistance of germ to bactericide, and the preventive effect of bactericide is descended.For overcoming the pesticide resistance of germ, adopt new bactericide kind and the mixed agent between bactericide to prevent and treat crop pest more.
Nitrile bacterium azoles is a kind of azoles fungicide that China develops recently, and it has low toxicity, characteristics such as efficient, and its mechanism of action is to suppress the sterol demethylation of germ spore, inhale therapeutic action in the tool, fungicidal spectrum is wide, to wheat powdery mildew, smut, and apple scab, powdery mildew, anthracnose; Uncinula bacterium on the crops such as grape all has good preventive effect.Because its preventive effect is good, in recent years, nitrile bacterium azoles particularly when apple scab was sent out greatly in 1998,1999, has played good effect to the harm of controlling and prevent and treat this germ in China's wide popularization and application.But nitrile bacterium azoles faces the drug-fast problem of germ equally, how to delay germ to its drug-fast generation, prolongs its service life, just becomes the problem that study.
The objective of the invention is at the problems referred to above, proposed a kind of method that delays germ to the drug-fast generation of nitrile bacterium azoles, be about to nitrile bacterium azoles and other fungicide compoundings and form new composition pesticide.
Below narrate main contents of the present invention:
A kind of microbicide compositions that contains nitrile bacterium azoles, said composition are by nitrile bacterium azoles and the formulated binary built bactericide of other any bactericide.
Other any bactericide of the present invention can be tmtd, ziram, ferbam, maneb, zineb, mancozeb, ethyl phosphine aluminium, asomate, thiophanate-methyl, tpn, enemy can pine, known any in the bactericide any one of can be used as of carbendazim, the mould spirit of evil, procymidone, metalaxyl, sulphur and other.
A kind of bactericidal composition that contains nitrile bacterium azoles is characterized in that containing the nitrile bacterium azoles of 1-10% and other bactericide of 5-50%.
A kind of bactericidal composition that contains nitrile bacterium azoles, the method that the ordinary person knows in its available this area is made the Multiple Pesticides formulation, as wetting powder, fine granule, missible oil, suspension emulsion etc.Below be that example is illustrated with the wetting powder that contains nitrile bacterium azoles:
A kind of wetting powder that contains nitrile bacterium azoles is characterized in that each components contents of this wetting powder is (percentage by weight):
Nitrile bacterium azoles: 1-10%
Other bactericide: 5-50%
Filler: 40-75%
Auxiliary agent: 5-15%
Filler of the present invention can be that white carbon, bentonite, talcum powder, diatomite, precipitated calcium carbonate etc. well known to a person skilled in the art material.
Auxiliary agent of the present invention can be wetting agent such as lignin sulfonic acid salt, soap class, alkyl sulfonates, laruyl alcohol; Suspending agent such as sodium phosphate trimer, draw back a kind of in powder, sodium silicate, carboxymethyl cellulose, xanthans, the polyaryl phenol polyethenoxy pyrophosphoric acid or several composition arbitrarily.
A kind of manufacture method that contains nitrile bacterium azoles wetting powder, this method is at first bulk myclobutanil, other bactericide original drugs, filler and insecticides adjuvant fully to be mixed in mixer, method with comminution by gas stream or ultramicro grinding is crushed to 95% mistake, 325 mesh sieves with this mixture again, and crushed material is this microbicide compositions.
The preparation and the processing method of other formulation of the present invention are not enumerated one by one at this, and those skilled in the art should be able to make other formulation by the composition content of effective scope that the present invention provides.
The present invention compares than prior art has following typical advantages:
1, delays germ to the drug-fast generation of nitrile bacterium azoles.
2, bactericidal composition of the present invention is by composite control spectrum and the control efficiency of having enlarged.Really.
3, synergistic effect is remarkable.
Be described in detail the present invention by the following examples:
One: 20% nitrile bacterium of embodiment azoles thiram wettable powder
Take by weighing the former powder 2kg of nitrile bacterium azoles (pure), tmtd 18kg (pure), sodium lignin sulfonate 5kg, precipitated calcium carbonate 75kg is crushed to 95% with comminution by gas stream after mixing and crosses 325 mesh sieves, promptly obtains 20% nitrile bacterium azoles thiram wettable powder.Inhale treatment and protection double action in said preparation has, can be widely used in the control of the fungal disease on the various crops, 1000 times of liquid of said preparation show very high preventive effect to the scab on apple, pears, the cucumber.
Two: 40% nitrile bacterium of embodiment azoles ethyl phosphine aluminium wetting powder
Take by weighing the former powder 6kg of nitrile bacterium azoles (pure), ethyl phosphine aluminium 34kg (pure), sodium lignin sulfonate 6kg, yellow first glue 4kg, bentonite 50kg fully mixes after be crushed to 95% and crosses 325 mesh sieves, promptly gets 40% nitrile bacterium azoles ethyl phosphine aluminium wetting powder.2000 times of dilutions of said preparation can be prevented and treated apple mildew, anthracnose; Tomato blight; Multiple diseases such as wheat powdery mildew.
Three: 50% nitrile bacterium of embodiment azoles mancozeb wettable powder
Take by weighing the former powder 5kg of nitrile bacterium azoles (pure), mancozeb 45kg (pure) saponin 5kg, carboxymethyl cellulose 1kg, dodecyl sodium sulfate 4kg, diatomite 40kg is after fully mixing, be crushed to 95% through airslide disintegrating mill and cross 325 mesh sieves, promptly get 50% nitrile bacterium azoles mancozeb wettable powder.Said preparation has protection and treatment double action to the crop fungal disease.Can be widely used in the various fungal diseases on the various crops.
