Description
Technical field
The present invention relates to a kind of bactericidal composition of synergy and the purposes for controlling plant diseases thereof.
Background technology
In recent years, because the plantation frequency of agriculture plantation is progressively strengthened, the generation of soil-borne disease is more and more general, seriously have impact on the yield and quality of agricultural product.The soil-borne diseases such as root rotof flax, bakanae disease of rice, cotton seedling blight have become the key factor of restriction respective crop plantation.At present, the medicament preventing and treating soil-borne disease mainly contains the medicament such as carbendazim, tmtd, hymexazo, because of these medicaments of single administration all the year round, has caused the highly resistant of pathogen, constantly result in the rampant again of disease.Therefore, efficiently, the pesticide species of safety, environmental protection is the indispensable means of the plant disease comprehensive regulation.
Fludioxonil is a kind of broad-spectrum touch-out type bactericide, derives from the pyrrolnitrin of natural products.The transfer of its major effect glucose phosphorylated, hinders mycelia metabolism, thus causes germ dead.It is mainly used in seed treatment, can prevent multiple diseases, as the disease that Alternaria, Ascochyta, aspergillus, Fusarium, Helminthosporium, Rhizoctonia and Penicillium bacterium etc. cause.Also can be used for foliar spray, its result is novel, and with existing bactericide without cross resistance, but its cost be used alone is high, is not easily accepted by user.
Trichlamide is a kind of novel agricultural bactericide, all has and extremely strong kills ability, can prevent and treat melon, the fungal disease such as beans fusarium wilt, damping off, anthracnose, epidemic disease, also can be used as soil disinfectant fungus and bacterium.Though the control spectrum of trichlamide is many, control efficiency is general, and chronic administration easily causes the resistance of germ.
Summary of the invention
For solving soil-borne disease unmanageable problem, the present invention provides a kind of pesticide combination scheme being convenient to efficient, cheap, the environmental protection of agricultural production application in advance.This combination can play both synergistic effect, improves control efficiency, can reduce respective cost again, saves Pesticide use amount.Test through a large amount of raw test repeated, filtered out the compounded combination of fludioxonil and trichlamide, obvious synergistic effect is all shown to banded sclerotial blight, damping off, fusarium wilt etc.

Embodiment
The embodiment provided below for elaborating the present invention, and does not form limiting the scope of the invention.All any amendments done within the spirit and principles in the present invention, variation all should within protection scope of the present invention.Test method used by embodiment, if without specified otherwise, is conventional method; Percentage composition in embodiment, if without specified otherwise, is mass percentage.
Biologicall test example 1: fludioxonil and the composite Toxicity Determination to rice sheath blight disease of trichlamide
Subjects: rice sheath blight disease (Rhizoctoniasolani), is gathered by field, through indoor separation and purification.
Test method: with reference to " People's Republic of China (PRC) agricultural industry criteria NY/T1156.2-2006 ", i.e. mycelial growth rate method.With the former medicine of acetone solution, 0.1% Tween 80 water dilution, is prepared into 6 series mass concentration.Aseptically, get the liquid 5mL configured and mix with 75mL medium, make 4 pastille flat boards, mix in contrast with medium with equivalent sterile water.Cultured germ is aseptically cut bacterium cake with the sterilizing card punch of diameter 5mm from edge.With inoculator, pure culture biscuits involvng inoculation is dull and stereotyped central in pastille, mycelia faces down, and is placed in 25 DEG C of incubators.Depending on blank growing state investigation result, each bacterium colony right-angled intersection method vertical survey diameter is each once gets its mean value, calculates mycelial growth inhibition rate.
Mycelial growth inhibition rate=(blank bacterium colony increases diameter-chemicals treatment bacterium colony and increases diameter) × 100/ blank bacterium colony increases diameter.
Concentration EC in suppression is calculated by method of least squares
50, then calculate co-toxicity coefficient (CTC) according to the abundant method of Sun Yun.As CTC < 80, then composition shows as antagonism, and as 80 < CTC < 120, then composition shows as summation action, as CTC > 120, then composition shows as synergistic effect.
Actual measurement toxicity index (ATI)=(standard agent EC
50/ reagent agent EC
50) × 100
In theoretical toxicity index (TTI)=A medicament toxicity index × mixture A percentage composition+B medicament toxicity index × mixture in the percentage composition of B
Co-toxicity coefficient (CTC)=[the theoretical toxicity index (TTI) of mixture actual measurement toxicity index (ATI)/mixture] × 100
Toxicity test the results are shown in Table 1.
