Abstract
The present invention discloses a kind of pesticide composition containing fenhexamid, comprise active components A and the fungicidal composition of activeconstituents B, active components A is selected from fenhexamid, activeconstituents B is selected from any one compound following: prochloraz and salt, imazalil, thiabendazole, thiophanate_methyl, derosal, and the weight ratio of active components A and activeconstituents B is 1: 80��60: 1. Multiple diseases in various crop is had greater activity by the present composition, and has obvious synergism, expands fungicidal spectrum. And have that dosage is little, resistance of rainwater washing against, the obvious feature of synergy.
Description
Technical field
The invention belongs to technical field of pesticide, it relates to the application of a kind of pesticide composition containing fenhexamid in crop pest.
Technical background
Fenhexamid (Fenhexamid) chemical name: N-(the chloro-4-hydroxy phenyl of 2,3-bis-)-1-methyl-cyclohexyl base methane amide, molecular formula: C14H17Cl2NO2. A kind of acid amide fungicides, seed treatment agent, nursery box treatment agent, belongs to interior suction, protectiveness sterilant. Different from existing sterilant, without fungicidal activity, do not suppress the growth of pathogenic bacteria mycelia. Check melanin biosynthesizing and can accelerate plant antibiotic after bacteria infection such as the generation of momilactoneA and sakuranetin, other diseases may also be had activity by this kind of mechanism of action indication ring propionyl bacterium amine. Infect, with paddy rice epidemic disease, the phytoalexin produced by increasing and improve crop resistibility.
Prochloraz and salt (Prochloraz) chemical name thereof: N-propyl group-N-[��-(2,4,6-trichlorine phenoxy group)-1H-imidazoles-1-methane amide, molecular formula: C15H16Cl3N3O2. Prochloraz and salt thereof are imidazoles broad-spectrum germicides, and the various crop disease caused for ascomycetes and imperfect fungi has special efficacy. By suppressing the biosynthesizing of sterol and cause effect. Although not having a systemic action, but it has certain conductive performance.
Imazalil (Imazalil) chemical name: 1-{2-(2,4 dichloro benzene base)-2-(2-propylene oxygen base) ethyl }-1H-imidazoles, molecular formula: C14H14Cl2N2O. Interior absorption wide-spectrum bactericide, this medicine affects cell membrane permeability, physiological function and lipid anabolism, thus destroys the cytolemma of mould. The formation of mould fungus inhibition spore simultaneously.
Thiabendazole (Thiabendazole) chemical name: ��-(4-thiazolyl)-1H-benzoglyoxaline, molecular formula: C10H7N3S. Mechanism of action is respiration and the cell proliferation of Antifungi plastosome, has just mutual resistance with the benzoglyoxaline medicament such as F-1991. Having Uptake and translocation effect, root executes the conduction of Shi Nengxiang top, but can not conduct to base. Anti-microbial activity is limited to ascomycetes, basidiomycetes, imperfect fungi, and to ovum bacterium and zygomycetes non-activity.
Thiophanate_methyl (Thiophanate-methyl) chemical name: 1,2-pair-(3-ethoxycarbonyl-��-thioureido) benzene, molecular formula: C12H14N4O4S2. Belong to benzimidazoles, it is a kind of broad spectrum systemic fungicide, various crop disease can be prevented and treated, there is interior suction, preventive and therapeutic action. It is converted into derosal in plant materials, and in the mitotic division of interference bacterium, the formation of spindle body, affects cell fission.
Derosal (Carbendazim) chemical name: N-(2-benzimidazolyl-) Urethylane, molecular formula: C9H9N3O2.High-efficiency low-toxicity, ascomycetes and imperfect fungi is effective, ovum bacterium and thin microbial disease is invalid, there is protection and therapeutic action. The mechanism of action be interference bacterium mitotic division in the formation of imitative hammer body, thus affect cell fission.
In the actual procedure of agriculture production, the problem that controlling disease the most easily produces is the generation of disease drug resistance. Different varieties composition carries out composite, is prevent and treat the very common method of resistance disease. Not congruent carry out composite, according to practical application effect, judge certain composite be synergy, add and or antagonistic action. In most cases, the composite effect of agricultural chemicals is all additive effect, really has the seldom composite of synergism, especially synergism clearly, very high composite just less of synergy ratio. Study through contriver, find mutually composite to fenhexamid and prochloraz and salt, imazalil, thiabendazole, thiophanate_methyl, derosal, there is good synergism within the specific limits, and about fenhexamid and prochloraz and salt thereof, imazalil, thiabendazole, thiophanate_methyl, derosal relevant composite, there is not yet relevant report at present at home and abroad.
Summary of the invention
It is an object of the invention to propose a kind of to there is the good pesticide composition containing fenhexamid of synergistic function, use cost effect low, anti-.
The present invention is achieved through the following technical solutions:
A kind of pesticide composition containing fenhexamid, it is characterized in that comprising active components A and activeconstituents B, active components A and activeconstituents B weight ratio are 1: 80��60: 1, described active components A is selected from fenhexamid, the one that activeconstituents B is selected from prochloraz and salt, imazalil, thiabendazole, thiophanate_methyl, derosal.
The described pesticide composition containing fenhexamid, it is characterised in that: the weight ratio of active components A and activeconstituents B is 1: 50��30: 1.
The described pesticide composition containing fenhexamid, it is characterised in that:
The weight ratio of fenhexamid and prochloraz and salt thereof is 1: 10��10: 1;
The weight ratio of fenhexamid and imazalil is 1: 10��10: 1;
The weight ratio of fenhexamid and thiabendazole is 1: 15��5: 1;

The embodiment of the present invention is the method adopting Toxicity Determination and field test to combine.First pass through Toxicity Determination, synergy ratio (SR) after clear and definite two kinds of medicaments are composite by a certain percentage, SR < 0.5 is antagonistic action, 0.5��SR��1.5 are summation action, SR > 1.5 is synergism, on this basis, then carry out field test.
Test method: determine after the effective inhibition concentration scope of each medicament through prerun, medicament establishes 5 dosage process respectively by active constituent content, if clear water comparison. Carry out with reference to " farm-chemical indoor determination test rule sterilant ", adopt mycelial growth rate method to measure medicament to the virulence of crop germ. Measure colony diameter with cross interior extrapolation after 72h, calculate each process net growth, mycelial growth inhibition rate.
Net growth (mm)=measurement colony diameter-5
Mycelial growth inhibition rate is converted into probit value (y), liquor strength (�� g/mL) converts logarithmic value (x) to, try to achieve virulence regression equation (y=a+bx) with method of least squares, and thus calculate the EC of often kind of medicament50Value. Calculating two medicaments different ratio synergy ratio (SR) according to Wadley method, SR < 0.5 is antagonistic action, and 0.5��SR��1.5 are summation action simultaneously, and SR > 1.5 is synergism. Calculation formula is as follows:
Wherein: a, b are respectively active components A and activeconstituents B ratio shared in combination;
A is fenhexamid;
B selects to the one in prochloraz and salt, imazalil, thiabendazole, thiophanate_methyl, derosal.
