Abstract

The invention relates to an agricultural and gardening antifungal composition, in particular to an antifungal composition containing benzamidoxime derivatives and triazoles. The composition comprises an active component A and an active component B), wherein the active component A) is one or more benzamidoxime derivatives represented by a formula (I); and the active component B) is one or more triazoles represented by a formula (II).

Description

A kind of agricultural and garden antifungal composition
Technical field
A kind of agricultural of the present invention and garden antifungal composition relate to the Fungicidal composition, particularly a kind of benzamidoxime derivative and mycocidal bactericidal composition of triazole type of containing that a kind of agricultural and gardening are used.
Background technology
In recent years, because single drug and the medication of non-science, cause many diseases that the agricultural chemicals of current use has been produced resistance, as the powdery mildew of cereal, melon, drupe class, grape, flowers etc., become a great problem of chemical control.Simultaneously frequent dispenser causes peasant burden to increase the weight of and increasing environmental pollution again.Therefore be badly in need of the antifungal new varieties of efficient, low toxicity, environmental protection.
Be the sustainable development of assurance agricultural production and the service life that prolongs medicament, seek the method for preventing and treating that has prevention and delaying drug resistance generation and can do with the resistance pathogen and seem particularly important.
Preventing and treating pathogen with the novel pesticide that does not have cross resistance is a good solution.But develop a novel pesticide at present and need screen 10,000-1.2 ten thousand compounds, hundred million dollars of expensive 1.2-1.5, the construction cycle is 5-10, is difficult to catch up with the speed that the pathogen resistance produces.Other method such as crop allocation adjustment, different agricultural chemicals are rotated etc., in the process of practical operation, are difficult to really play obvious effects.
By the preparation of the benzamidoxime derivative of formula (I) expression and to the effect of harmful germ by document known (JP2696342, WO96/19442, CN1170404).
Figure BSA00000323701900011
Triazole type antifungal bactericidal mechanism principle is very complicated, mainly is the biosynthesis that suppresses the thalline ergosterol, thereby the growth, the growth of mycelia and the formation of spore that suppress or disturb thalline to adhere to spore and haustorium.Better to the powdery mildew effect, but the risk that exists resistance to strengthen.
The mycocidal combination of benzamidoxime derivative and triazole type is disclosed among the EP1625790.Document shows that said composition has obvious synergistic effect.But its disclosed benzamidoxime derivative and the mycocidal percentage by weight of triazole type are 1: 0.01-1,000, preferred 1: 1-100, scope is too wide, and is inapplicable when agricultural is specifically used.
Summary of the invention
The objective of the invention is at above-mentioned weak point, the Fungicidal composition that provides a kind of agricultural and gardening to use uses on a kind of suitable agricultural, disease is had the efficient bactericidal composite that synergistic effect is arranged of outstanding control efficiency.
By a large amount of biologicall test screenings, found the mass ratio of the best when benzamidoxime derivative and triazole class compounds are composite.When benzamidoxime derivative and triazole type antifungal were composite, mass ratio was 1: 1-1:, be preferably 1 at 15 o'clock: 5-1: 10 o'clock, and to control efficiency the best of disease.

Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, the present invention describes with following specific embodiment, but the present invention is limited to these examples absolutely not.
The agricultural chemicals of different cultivars shows three kinds of type of action: summation action, synergistic effect and antagonism after mixing usually.But be specially which kind of effect, unpredictable, have only by a large amount of experiments and just can know.Compound synergic is well filled a prescription, owing to obviously improved actual control efficiency, reduced the usage amount of agricultural chemicals, thereby delayed the generation of disease drug resistance greatly, and be the important means of integrated control.
The present composition is active ingredient with benzamidoxime derivative and triazole bactericidal agent, the combination antagonism property of medicine has obvious role in synergism between them, and be not only the simple addition of two kinds of medicament effects, specifically be illustrated with following biologicall test example.
Biologicall test example 1: cyflufenamid and Tebuconazole composite toxicity test and proportioning screening at wheat powdery mildew
Laboratory reference " pesticide bioassay technology " (old spring chief editor, publishing house of Beijing Agricultural University publishes), and " agricultural chemicals indoor bioassay experiment criterion NY/T1156.2-2006 ". this experiment adopts the wheat powdery mildew dish to plant determination method.On the basis of preliminary experiment, select 2 leaf periods, the consistent melon seedling of growing way, write tag number, insert in the potted plant seedling basin with permanent pen, discharging according to the order of sequence, adopt the foliar spray method, medicament is sprayed on the seedling leaf, will tries material after spraying is handled and in fume hood or greenhouse, dry in the shade and inoculate behind the 24h.Cultivate 7d investigation prevention result in the greenhouse, grade scale is carried out State Standard of the People's Republic of China " pesticide field efficacy medicine test criterion () ", calculates control efficiency with disease index, carries out statistical analysis with the DPS data processing software, calculates the EC of each medicament 50, press the abundant method of Sun Yun then and calculate co-toxicity coefficient (CTC).
When CTC≤80, then compositions table reveals antagonism, and when 80<CTC<120, then compositions table reveals summation action, and when CTC 〉=120, then compositions table reveals synergistic effect.
Actual measurement toxicity index (ATI)=(standard medicament EC 50/ reagent agent EC 50) X100
The percentage composition of B in percentage composition+B medicament toxicity index X mixture of A in theoretical toxicity index (TTI)=A medicament toxicity index X mixture
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (the ATI)/theoretical toxicity index (TTI) of mixture] X100
