Abstract
The invention relates to a pesticide composition which comprises chlorantraniliprole and fluoxastrobin which serve as effective components. The weight ratio of chlorantraniliprole to fluoxastrobin is 1: 10-10: 1; the weight percentage of the total weight of chlorantraniliprole and fluoxastrobin in the pesticide composition is 1 to 80 percent. In actual use, the pesticide composition is prepared into a suspending agent and granules, is suitable for preventing and controlling rice sheath blight disease and rice fulgorid, and has an obvious synergistic effect; the use amount of pesticides is reduced, and generation of the pesticide resistance of disease and pest injuries can be relieved.
Description
Technical field
The present invention relates to composition pesticide and application thereof, specifically a kind of Rynaxypyr and fluoxastrobin are the composition pesticide of active ingredient, for the water prevention rice sheath blight, rice fulgorid.
Background technology
Rynaxypyr, belongs to O-formammidotiazol-benzamide insecticide.Mainly activate blue Buddhist nun's alkali acceptor, the calcium ion of release smooth muscle and the interior storage of striated muscle cell, causes muscle to regulate weak, paralysis, until last insect death.This active ingredient shows mammal and the extremely significant selective difference of insect blue Buddhist nun's alkali acceptor, substantially increases mammal and other vertebrate safeties.
Fluoxastrobin belongs to methoxy acrylic bactericide, and the mechanism of action of fluoxastrobin is also mitochondrial respiratory inhibitor, namely suppresses mitochondrial breathing by electro transfer between cytochrome b and C1.Fluoxastrobin application optimum period, is wide, no matter early stage as spore germination, germ tube growth and intrusion leaf portion at fungal infection, or can provide extraordinary protection and therapeutic action at growth period of hypha; But infect the most effective to spore germination and initial stage.The systemic activity of the excellence that cause has, it can be rapidly absorbed, and can transmit to top equably in leaf portion, therefore have the good resistance of rainwater washing against ability of root.
Rice sheath blight disease is commonly called as " flower pedopathy ", is infected by Rhizoctonia solani Kuhn to fall ill, how occurs under high temperature, super-humid conditions.Banded sclerotial blight causes harm seriously in South Rice Region of China, is one of Major Diseases in current Rice Production.The scab ellipse of leaf sheath, blade or Colaesce are the large spot of moire shape, and time moist, scab is blackish green, moistening shape.Scab edge dark brown time dry, middle part olive drab(O.D), to canescence, causes leaf sheath and blade is withered eventually.Especially occur the most general with the high yield field of dense planting hybrid rice of short stem and seriously, the withered Seed-Setting Percentage in Rice that causes of blade reduces, and thousand kernel weight alleviates, and generally causes damage 10 ~ 20%, notably can reach more than 50%.
Summary of the invention
The object of the present invention is to provide a kind of compound synergic composition containing Rynaxypyr and fluoxastrobin, for the water prevention rice sheath blight, rice fulgorid.
Technical scheme: for achieving the above object, the invention provides a kind of composition pesticide containing Rynaxypyr and fluoxastrobin, active ingredient is Rynaxypyr and fluoxastrobin, the weight ratio of Rynaxypyr and fluoxastrobin is 1:10 ~ 10:1, Rynaxypyr and fluoxastrobin weight summation percentage by weight are in the composition 1% ~ 80%, and all the other are allow in agricultural chemicals to use and acceptable auxiliary element.
Described auxiliary element is one or more the combination in solvent, emulsifier, wetting agent, dispersant, stabilizing agent, antifreezing agent, thickener, disintegrant, binding agent, defoamer, bleeding agent, synergist, fire retardant, density adjuster and filler, above material is known substance conventional in pesticidal preparations, change to some extent according to being prepared into the different formulations of pesticide, but be not particularly limited.
Composition pesticide of the present invention can be prepared into any one formulation that applicable agricultural production uses by known method, reasonable formulation has suspending agent, granule.
The production technology of described composition pesticide application forms all belongs to existing known technology, does not repeat them here.
Composition pesticide provided by the invention, is applied to the water prevention rice sheath blight, rice fulgorid.
Compared with prior art, the invention has the advantages that:
1, Rynaxypyr and fluoxastrobin is composite has beyond thought synergistic function, is used alone the control efficiency that improve insect and germ than single dose;
2, Rynaxypyr and the fluoxastrobin mechanism of action different, mixed can delay insect and the drug-fast generation of germ;
3, Rynaxypyr and fluoxastrobin two kinds of active ingredients composite, decrease Pesticide use amount, reduce use cost and alleviate pollution to environment.
Embodiment
In order to understand essence of the present invention better, below in conjunction with embodiment, content of the present invention is described further, but can not limitation of the present invention be considered as.
Embodiment 1: synergy evaluation.
Evaluate drug combination mode according to Gowing method, its formula is as follows:
E
0﹦X﹢Y–XY/100
In formula, X be Rynaxypyr alone with certain dosage time control rate to target pest; Y be fluoxastrobin alone with certain dosage time to target fungus inhibiting rate; E
0for the theoretical value to target inhibiting rate when Rynaxypyr, fluoxastrobin two kinds of pharmacy mix; Measured value to target inhibiting rate when E is Rynaxypyr, fluoxastrobin two kinds of pharmacy mix.
Evaluation criterion: as E – E
0during > 10%, be expressed as synergistic effect; As ﹣ 10%≤E – E
0when≤10%, show as summation action; As E – E
0during < ﹣ 10%, show as antagonism.
Table 1, rice hoppers synergy to be evaluated.
Table 2, rice sheath blight disease synergy to be evaluated.
Above-mentioned test shows, Rynaxypyr, fluoxastrobin are composite according to the ratio of 1:10-10:1, all shows synergistic effect to rice sheath blight disease, rice fulgorid.
Embodiment 2:20% Rynaxypyr fluoxastrobin suspending agent.
Embodiment 3:3% Rynaxypyr fluoxastrobin granule.
Embodiment 4: field control effectiveness test.
Adopt above-mentioned 20% Rynaxypyr fluoxastrobin suspending agent, 3% Rynaxypyr fluoxastrobin granule medicament water prevention rice rice fulgorid, banded sclerotial blight, test site is Guangdong Huizhou city, test period is in August, 2013, select the field that morbidity is comparatively serious, adopt the mode of mechanical spraying.With 20% Rynaxypyr suspending agent, 1500 times of liquid, 24% fluoxastrobin suspending agent, 1500 times of liquid for contrast medicament.Test process is carried out with above-mentioned 20% Rynaxypyr fluoxastrobin suspending agent 1500 times of liquid, 3% Rynaxypyr fluoxastrobin granule 400 grams/acre.Investigate preventive effect respectively at 1d, 3d, 7d, 20d after medicine, after medicine, 3d preventive effect calculates in strict accordance with the computational methods of regulation in National Standard of the People's Republic of China's " pesticide efficacy field trial criterion ".Above medicament 7d post-equalization preventive effect sees the following form.Test shows that 20% Rynaxypyr fluoxastrobin suspending agent, 3% Rynaxypyr fluoxastrobin granule have rice sheath blight disease, rice fulgorid and well prevents and treats therapeutic action.
Table 3, field control effectiveness test result.
Shown by indoor biometrics test and a large amount of outdoor field comparison test, 20% Rynaxypyr fluoxastrobin suspending agent, 3% Rynaxypyr fluoxastrobin granule have good control efficiency to rice sheath blight disease, rice hoppers, are that one is worth of widely use pesticide species.
