Abstract
The invention discloses the composition of a kind of Boscalid and chlorine nalidixic bacterium ester, said composition is with Boscalid and chlorine nalidixic bacterium ester for active component, and its mass ratio is 100:1 ~ 1:100.Composition of the present invention alleviates existing phytopathogen respectively to the potential resistance risk of chlorine nalidixic bacterium ester and Boscalid, after Boscalid and chlorine nalidixic bacterium ester are combined, therebetween there is obvious synergy, additionally reduce dosage simultaneously, thus make said composition can be widely used in preventing and treating sclerotinia rot of colza, the banded sclerotial blight of paddy rice and rice blast, wheat sharp eyespot, wheat scab, wheat powdery mildew, fruits and vegetables powdery mildew, gray mold, apple canker, dry rot, anthracnose, ring spot and spot defoliation, the anthrachose of grape of grape, anthracnose and ring spot etc.
Description
One, technical field
The invention belongs to pesticide field, be specifically related to a kind of composition containing Boscalid and chlorine nalidixic bacterium ester.
Two, background technology
Boscalid (SYPdioxonil) is a class Novel tobacco amide-type systemic fungicide, fungicidal spectrum is wider, almost there is activity to all types of fungal disease, to preventing and treating, powdery mildew, gray mold, stalk break and various rots etc. are very effective, and also effective to the resistance bacterium of other medicaments, be mainly used in the control comprising the diseases such as rape, grape, fruit tree, vegetables and field crop.It stops fungi production capacity by Profilin matter complex II, thus Antifungi growth.Spore germination, the extension of tube, the growth of mycelia and spore mother cell can be suppressed to form the Main Stage such as the Growth and reproduction of fungi, being first utilizes this efficient mode of action to resist the product appearing at novel disease on important crops, even if cause of disease private savings create the resistance to other bactericide, the control of Boscalid also can be subject to.Because its distinctive mechanism of action not easily produces cross resistance, in addition to crop safety and favourable toxicity data and ecological effect, be the Novel tobacco acid amide fungicides of significant.
Chlorine nalidixic bacterium ester is novel methoxy acrylic (QoI) bactericide of Shenyang Chemical Engineering Inst's research and development, has that fungicidal spectrum is wide, the lasting period is long, bactericidal activity is high; To crop and Environmental security.There is excellent bacteriostatic activity, as southern corn leaf blight, Pyricularia oryzae, rice false smut, Rhizoctonia solani Kuhn, Cochliobolus sativus, botrytis cinerea, Sclerotinia sclerotiorum, Peronophythora Litchii germ etc. have all showed good bacteriostatic activity to the fungi of sac fungi, imperfect fungus and Basidiomycetes; Excellent prevention, treatment and eradicant action is gone out at variable rate technology.
Three, summary of the invention
The object of this invention is to provide composition that a kind of disease to multiple kinds of crops all has preventive and therapeutic effect, that be main active substances with Boscalid and chlorine nalidixic bacterium ester, alleviate the potential resistance risk of existing pathogen to chlorine nalidixic bacterium ester and Boscalid, result of study shows Boscalid or has obvious synergy with the combination of chlorine nalidixic bacterium ester.
Object of the present invention can be reached by following measures:
Containing a composition for Boscalid and chlorine nalidixic bacterium ester, said composition is with Boscalid and chlorine nalidixic bacterium ester for active component, and its mass ratio is 100:1 ~ 1:100; The mass ratio of Boscalid and chlorine nalidixic bacterium ester is preferably 10:1 ~ 1:100, is further preferably 10:1 ~ 1:30, most preferably 10:1 ~ 1:10.
Wetting powder, suspending agent or aqueous emulsion can be joined to obtain add insecticides adjuvant in active component Boscalid and chlorine nalidixic bacterium ester after.As added auxiliary agent and after regulating pH value 5 ~ 7, be made into wetting powder in active component Boscalid and chlorine nalidixic bacterium ester.Chlorine nalidixic bacterium ester and Boscalid can adopt former medicine.Insecticides adjuvant can select one or more in wetting agent, dispersant, filler, binding agent, disintegrant etc.
Composition of the present invention alleviates existing phytopathogen respectively to the potential resistance risk of chlorine nalidixic bacterium ester and Boscalid; By Boscalid or after combining with chlorine nalidixic bacterium ester, therebetween there is obvious synergy, additionally reduce dosage simultaneously, thus make said composition can be widely used in preventing and treating sclerotinia rot of colza, the banded sclerotial blight of paddy rice and rice blast, wheat sharp eyespot, wheat scab, wheat powdery mildew, fruits and vegetables powdery mildew, gray mold, apple canker, dry rot, anthracnose, ring spot and spot defoliation, the anthrachose of grape of grape, anthracnose and ring spot etc.
