Abstract
The invention relates to a bactericidal composition containing picoxystrobin and amino-oligosaccharin, usage and an application thereof and belongs to the field of pesticides. Pharmacodynamic components of the bactericidal composition contain picoxystrobin and amino-oligosaccharin, wherein the ratio of picoxystrobin to amino-oligosaccharin by weight part is 50:1-1:30. After the two components picoxystrobin and amino-oligosaccharin are blended, the bactericidal composition has effects of preventing and curing plant diseases. As picoxystrobin and amino-oligosaccharin have different mechanisms of action, a synergistic effect shows, prevention and curing range of diseases is broadened, dosage is reduced, use cost is decreased, and generation of resistance is alleviated.
Description
Technical field
The invention belongs to pesticide field, relate to bactericidal composition and using method and application that a kind of main active is ZEN 90160 and amino-oligosaccharide.
Background technology
ZEN 90160, English common name (Picoxystrobin), molecular formula: C
18H
16F
3NO
4, chemical name: (E)-3-methoxyl group-2-{2-[6-(trifluoromethyl)-2-pyridine oxygen methyl] phenyl } methyl acrylate.The mitochondrial respiratory inhibitor namely shifts by electronics between cytochrome b and c1 and suppresses mitochondrial breathing.Control is effective to the bacterial strain that 14-demethylation enzyme inhibitor, benzamides, dicarboxylic dihydrazides amine and benzimidazole produce resistance.
Amino-oligosaccharide, English name (oligosacch alins), molecular formula: (C

11O
4N) n(n 〉=2), chemical name: β-1,4-oligomerization-gucosamine, be also referred to as oligosaccharide, shell oligosaccharide, chitosan oligomer, chitan, agricultural chitosan oligosaccharide, it is natural chitinous catabolite, a kind of bactericide with resistant effect that the microorganism belonging to genus metabolism is extracted, growth to germ has inhibitory action, but the disease resistance of amino-oligosaccharide inducing plant, multiple fungi, bacterium and virus are produced immunity and killing action, the diseases such as wheat mosaic, cotton verticillium wilt, rice blast, tomato blight are had good preventive and therapeutic effect.Simultaneously, amino-oligosaccharide has to a certain degree direct repression to the various plants pathogen; In addition, amino-oligosaccharide itself contains abundant C, N, can decompose be utilized by microorganism and as the nutrient of plant growth; Amino-oligosaccharide can change soil microflora, and the promotion beneficial microorganism is grown and suppressed some phytopathogens; But the growth of amino-oligosaccharide stimulating plant makes crops and fruit and vegetable volume increase good harvest.
The ZEN 90160 single dose is used for a long time, and disease is developed immunity to drugs, and causes the problem that dosage strengthens, preventive effect reduces, the lasting period shortens, and is unfavorable for environment sustainable development.And that the active ingredient of the different mechanisms of action is carried out is composite, is to delay the disease method commonly used that develops immunity to drugs, and according to the effect in the production application, judge this composite be synergistic effect or antagonism.Complex role is significantly filled a prescription, and can obviously improve preventive effect, greatly reduces the dosage of agricultural chemicals, can also enlarge fungicidal spectrum, improves germicidal efficiency.Through inventor research, find can produce good synergistic effect after ZEN 90160 and amino-oligosaccharide is composite, and not yet open about ZEN 90160 and amino-oligosaccharide composite relevant report and application.
Summary of the invention
The objective of the invention is to find a kind ofly prevent and treat that spectrum is wide, effect is remarkable, cost is low, the bactericide good with Environmental compatibility.
Another object of the present invention provides using method and the purposes of this bactericidal composition.
Bactericidal composition of the present invention comprises two kinds of active ingredient components of the dosage that can produce synergistic activity, and suitable auxiliary material, it is characterized in that component ZEN 90160 and amino-oligosaccharide.
The effective component that contains the bactericidal composition of ZEN 90160 and amino-oligosaccharide among the present invention is ZEN 90160 and amino-oligosaccharide, and wherein the ratio of weight and number of ZEN 90160 and amino-oligosaccharide is 50 ︰, 1～1 ︰ 30.Preferred version is: the ratio of weight and number of ZEN 90160 and amino-oligosaccharide is 50 ︰, 1～1 ︰ 1.
The bactericidal composition that contains ZEN 90160 and amino-oligosaccharide among the present invention is suspending agent, is comprised of the raw material of following parts by weight:
ZEN 90160 1.5-50 part;
Amino-oligosaccharide 1-45 part;
Surfactant 6-11 part;
Thickener 2-6 part;
Xanthans 1-3 part;
Antifreezing agent 3-5 part;
Water adds surplus to 100 part.
