Description
[technical field]
The invention belongs to agricultural insecticide technical field.More specifically, the present invention relates to a kind of insecticidal and bactericidal composition containing thifluzamide, and containing the insecticidal bactericide of described insecticidal and bactericidal composition, and described insecticidal and bactericidal composition and described insecticidal bactericide are in the application of water prevention chilo suppressalis and Rhizoctonia solani Kuhn.
[background technology]
Striped rice borer Chilo suppressalis (Walker) belongs to Lepidoptera, Pyralidae, that China paddy rice endangers one of Occurrence the most serious, be injured in tillering stage and cause withered sheath, withered heart seedling, be injured in the fringe phase and cause insect bite strain and dead ears, the general time underproduction 3% ~ 5%, time serious, the underproduction is more than 3 one-tenth.All there is distribution in domestic Ge Dao district, comparatively paddy stem borer and pink rice borer distribution wide, but mainly with the Yangtze river basin and on the south rice district occur heavier.
One of large disease of rice sheath blight disease Shi Shi China paddy rice three, in the whole nation, there is generation in each paddy rice producing region, and South Rice Region of China is very serious.Banded sclerotial blight all can occur to the fringe phase at rice seedling, causes harm the heaviest with tillering regularity to heading stage.The photosynthesis of this sick chief destructive rice strain, weakens root absorption ability, reduces the accumulation of nutriment, affects paddy rice solid.The withered sclerotium of line is sprouted naturally can infect 40 various plants, wherein mainly paddy rice, wheat, corn etc., and weeds parasitism mainly contains barnyard grass, trip grass etc.In general, early rice overweights Single Late Rice to rice pathogenesis, and double cropping late rice morbidity is lighter.The not plump paddy rate increase of field that morbidity is heavy, thousand kernel weight reduces, and underproduction 5-10%, serious can underproduction 50-70%.
Thifluzamide (Trifluzamide), belongs to thiazole amide bactericide, has strong Uptake and translocation and long lasting effect.Thifluzamide all has activity to pathomycetes such as Rhizoctonia, Puccinia, Ustilago, Tilletia, corticium, nuclear cavity Pseudomonas, especially has special efficacy to the fungus-caused disease of Basidiomycetes such as banded sclerotial blight, damping off etc.Can the mode such as foliar spray, seed treatment, soil treatment use.Thifluzamide all has good control efficiency to many kinds of fungal diseases, can be widely used in the various crop such as water paddy and wheat class, peanut, cotton, beet, coffee, potato, lawn.Production is mainly used in the banded sclerotial blight of preventing and treating paddy rice and wheat class.Further, it is more healthy and stronger that thifluzamide can make plant stem-leaf grow, and effectively can improve the resistance of crop.
Bisamide insecticides, by efficiently activating the calcium ion that insect ryanodine receptor makes in its excessive release cells in calcium storehouse, destroy insect cell device intra-and extra-cellular calcium ionic equilibrium, thus it is dead to cause insect to be paralysed.
Wherein, Rynaxypyr (chiorantraniliprole) is the insecticide that du pont company develops from o-amino benzoyl diamide compound, its mode of action is based on stomach toxicity, have certain action of contace poison concurrently, have good interior absorption and permeability, speed of action is fast, the lasting period is long.To the most of Lepidoptera, the coleopteran pest that endanger the crops such as cereal crops, fruit tree, vegetables, there is preventive and therapeutic effect that is quick, long-acting, wide spectrum, and toxicity is only micro-poison.
Bromine cyanogen insect amide (Cyantraniliprole), for the 2nd generation ryanodine receptor of E.I.Du Pont Company's exploitation suppresses insecticides, there is root absorption, can conduct in xylem, compared with Rynaxypyr, its applicable crops is more extensive, can prevent and treat pests with chewing mouthparts, can sucking pest be prevented and treated again, comprise Lepidoptera, Semiptera and coleopteran pest.
Four chlorantraniliproles, belong to ryanodine receptor activator insecticides, it is combined by ryanodine receptor in pest body, open calcium channel, make to be stored in intracellular calcium ion sustained release in sarcoplasm, calcium ion and sarcoplasm mesostroma protein combination, cause muscle contracts last.Insect bodies Symptoms is tic, food refusal, finally dead.Four chlorantraniliproles are low toxicity, broad spectrum pesticide, all have good activity to lepidoptera pest.
Traditional rice pest prevention and controls is mainly spray-on process, and labour intensity is high, and work efficiency is low, and water consumption is large, is difficult to the needs meeting large-scale planting; Along with the enforcement of China's land transformation policy, soil presents the trend of intensive management, and crop contiguous plant area increases; And China's population aging degree continues to increase now, between twenty and fifty Out-migrant for work mostly in rural area, agricultural labour becomes rare resource gradually, and human cost improves constantly, and the cost directly causing agricultural to become to produce continues to increase.
Granule is the granular preparation processed by auxiliary agents such as former medicine, carriers.During dispenser, there is directionality, make medicament fully reach target organisms and not threaten to beneficial organisms such as natural enemies; Powder is not attached on the cauline leaf of plant, avoids directly contact and produces poisoning; Without dust from flying during dispenser, both free from environmental pollution, the attachment of operating personnel's health can be reduced again or suck dose, avoiding intoxication accident; The rate of release of active ingredient in controlled granulation agent, 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, can not effectively double insect pest of curing the disease, and time-consumingly takes a lot of work, and the regulating action of most active ingredient to crop is little, and crop growing state is weak, and resistance against diseases is weak.Heavy in order to solve current paddy field dispenser work, granule prevention and elimination of disease and pests effect is single, control spectrum is narrow, needs medication repeatedly, little to the regulating action of crop, the problems such as crop disease-resistant ability is weak, the present patent application discloses a kind of insecticidal and bactericidal composition containing thifluzamide.

Table 3 water prevention chilo suppressalis and rice sheath blight disease field control effectiveness test
From the data in upper table 3, after thifluzamide and Rynaxypyr, bromine cyanogen insect amide, four chlorantraniliproles are composite, all high than thifluzamide, Rynaxypyr, bromine cyanogen insect amide, the preventive effect of four chlorantraniliprole single doses to rice-stem borer and banded sclerotial blight to the preventive effect of rice-stem borer and banded sclerotial blight, as can be seen here, obvious synergistic effect is had in field to the preventive effect of rice-stem borer and banded sclerotial blight after composite; Under identical active ingredient, same amount, the field efficacy of granule is apparently higher than the drug effect of suspending agent.
Above-mentioned indoor biometrics and field control effectiveness test result show that the beneficial effect that bactericidal composition of the present invention produces is:
(1) can notable synergistic after composite.Because it is more healthy and stronger that thifluzamide can make plant stem-leaf grow, effectively can improve the resistance of crop, after pesticide compositional, significantly improve the control efficiency of damage by disease and insect;
(2) the composite rear growth to seedling has obvious growth-promoting functions;
(3) the application target of composite rear expansion agricultural chemicals, killing pests and suppressing bacteria carries out simultaneously;
(4) prevent and treat rice pest, adopt seedling dish process or spread fertilizer over the fields, use conveniently, without the need to using machinery, time saving and energy saving, effectively reduce formulation rate.
