A kind of insecticidal and bactericidal composition containing thifluzamide

[technical field]

The invention belongs to agricultural insecticide technical field.More particularly it relates to an containing thiophene furan The insecticidal and bactericidal composition of amide, and the insecticidal bactericide containing described insecticidal and bactericidal composition, and Described insecticidal and bactericidal composition and described insecticidal bactericide are at preventing and treating rice-stem borer and Rhizoctonia solani Kuhn Application.

[background technology]

Striped rice borer Chilo suppressalis (Walker) belongs to Lepidoptera, Pyralidae, is to endanger on China Oryza sativa L. One of Occurrence that evil is the most serious, is injured in tillering stage and causes withered sheath, withered heart Seedling, be subject in the fringe phase Evil causes insect bite strain and dead ears, and the general time underproduction 3%~5%, time serious, the underproduction is more than 3 one-tenth.Domestic Ge Dao district all has distribution, relatively yellow rice borer and pink rice borer distribution wide, but mainly with the Yangtze river basin and on the south rice district send out Raw heavier.

One of big disease of rice sheath blight disease Shi Shi China Oryza sativa L. three, has generation in national each Oryza sativa L. producing region, South Rice Region of China is the most serious.Banded sclerotial blight all can occur to the fringe phase at rice seedling, with tillering regularity to heading Phase causes harm the heaviest.The photosynthesis of this sick chief destructive rice strain, weakens root absorption ability, reduces nutrition The accumulation of material, affects Oryza sativa L. solid.The withered sclerotium of stricture of vagina is sprouted naturally can infect 40 various plants, Qi Zhongzhu If Oryza sativa L., Semen Tritici aestivi, Semen Maydis etc., weeds parasitism mainly has barnyard grass, Herba leerisae hexandrae etc..Rice pathogenesis typically comes Saying, early rice overweights Single Late Rice, and double cropping late rice morbidity is lighter.The field hollow kernels rate of morbidity weight increases, and thousand Grain heavily reduces, and underproduction 5-10%, serious can underproduction 50-70%.

Thifluzamide (Trifluzamide), belongs to thiazole amide antibacterial, have strong Uptake and translocation and Long lasting effect.Thifluzamide is to Rhizoctonia, Puccinia, Ustilago, Tilletia, Fu Ge The pathomycetes such as Pseudomonas, nuclear cavity Pseudomonas are the most active, especially fungus-caused to Basidiomycetes disease such as stricture of vagina Rot, damping-off etc. have specially good effect.Can use in modes such as foliar spray, seed treatment, soil treatment. Thifluzamide all has good prevention effect to many kind fungal diseases, can be widely applied to water paddy and wheat The various crop such as class, Semen arachidis hypogaeae, Cotton Gossypii, Radix Betae, coffee, Rhizoma Solani tuber osi, lawn.It is mainly used in production Preventing and treating Oryza sativa L. and the banded sclerotial blight of wheat and barley.Further, thifluzamide can make plant stem-leaf growth more healthy and stronger, can It is effectively improved the resistance of crop.

Bisamide insecticides, by calcium in efficiently activation insecticide ryanodine receptor makes its excessive release cells Calcium ion in storehouse, destroys insect cell device intra-and extra-cellular calcium ionic equilibrium, thus causes insecticide paralysis death.

Wherein, Rynaxypyr (chiorantraniliprole) is that du pont company is from o-amino benzoyl The insecticide developed in diamide compound, its model of action, based on stomach toxicity, has concurrently certain Action of contace poison, has good interior absorption and permeability, and speed of action is fast, the lasting period is long.To harm grain Most of Lepidopteras of crop such as food crop, fruit tree, vegetable, coleopteran pest have quick, long-acting, The preventive and therapeutic effect of wide spectrum, and toxicity is only micro-poison.

Bromine cyanogen insect amide (Cyantraniliprole), the 2nd generation ryanodine receptor for E.I.Du Pont Company's exploitation presses down Insecticides processed, has root absorption, it is possible to conduct in xylem, compared with Rynaxypyr, its Applicable crops is the most extensive, can prevent and treat pests with chewing mouthparts, can prevent and treat again sucking pest, Including Lepidoptera, Semiptera and coleopteran pest.

Four chlorantraniliproles, belong to ryanodine receptor activator insecticides, its by with Ryanicide in pest body Receptor combines, and opens calcium channel, makes to be stored in intracellular calcium ion and be sustained release in sarcoplasm, Calcium ion and sarcoplasm mesostroma protein binding, cause muscle contracts last.Insect bodies Symptoms for twitch, Refusing to eat, finally dead.Four chlorantraniliproles are low toxicity, broad spectrum pesticide, are respectively provided with lepidoptera pest very Good activity.

Traditional rice pest prevention and controls is mainly nebulization, and labor intensity is high, and work efficiency is low, Water consumption is big, it is difficult to meet the needs of implantation in large scale;Along with the enforcement of China's land transformation policy, soil Ground presents the trend of intensive management, and crop contiguous plant area increases;And present China aged tendency of population Degree continues to increase, and between twenty and fifty Out-migrant for work mostly in rural area, agricultural labour force is increasingly becoming rare money Source, human cost improves constantly, and directly results in agricultural and becomes the cost produced to continue to increase.

Granule is the granular preparation processed by auxiliary agents such as former medicine, carriers.There is during dispenser directivity, Make medicament can sufficiently achieve target organisms and the beneficial organisms such as natural enemy not threatened;Powder is not attached to On the stem and leaf of plant, it is to avoid directly contact produces poisoning;Non-dusting during dispenser, neither pollutes ring Border, can reduce again the attachment of operator's health or suck dose, it is to avoid intoxication accident;In controlled granulation agent The rate of release of effective ingredient, extends the lasting period;Can directly spread fertilizer over the fields during use, time saving and energy saving.

At present, mostly the granule of domestic use is single insecticidal constituent or sterilization component, it is impossible to effective Double insect pest of curing the disease, time-consuming takes a lot of work, and most effective ingredient is little to the regulation effect of crop, crop growing state Weak, resistance against diseases is weak.Heavy in order to solve current rice terrace dispenser work, granule prevention and elimination of disease and pests is made Composing narrow with single, preventing and treating, need medication repeatedly, the regulation effect to crop is little, and crop disease-resistant ability is weak Etc. problem, the present patent application discloses a kind of insecticidal and bactericidal composition containing thifluzamide.
