Abstract
The invention discloses an insecticidal and bactericidal composition containing two kinds of active components; the first active component is fluorobenzene ether amide; the second active component is chloramine phosphorus. The insecticidal and bactericidal composition provided by the invention is low in toxicity and high in efficiency, is suitable for preventing and treating chilo suppressalis, rice sheath blight diseases and rice blast in a rice seedling stage, and has excellent insecticidal and bactericidal activity; while the dosage is reduced, the generation of drug resistance is delayed, and the lasting period is prolonged.
Description
Technical field
The invention belongs to pesticide field, specifically fluorobenzene ether amide and chloramine phos are combined for the pesticide-germicide of active ingredient
Thing.
Background technology
In China's early spring, temperature is very unstable, when rice seedling meets with microthermal climate, water logging, paddy rice
Often there is seedling rot phenomenon in seedling Jing.Jing is investigated, and the main cause that seedling rot occurs is banded sclerotial blight, rice blast, bacterial wilt etc..Additionally, water
, on the occasion of the overwinter generation rice stem borer spawning and hatching stage, larva will also infect hazard rice for rice seedling, seedling stage.On southern ground
The merging generation such as area, rice seedling stage striped rice borer, banded sclerotial blight, rice blast, damping-off, bakanae disease is increasingly severe, to agricultural
Production brings considerable influence.
Fluorobenzene ether amide is Central China Normal University's pyrazol acid amide compounds newly developed, to cucumber, tomato, potato etc.
The diseases such as epidemic disease, downy mildew, the tikka of plant have good prevention effect, while the banded sclerotial blight, powdery mildew to paddy rice and wheat
Etc. there is good preventive effect.Field test shows do not have cross resistance with existing bactericide.Shown in structural formula following (I).
。
Chloramine phos are by Zhejiang Lesi Chemical Co., Ltd. and Wuhan Engineering Univ's joint research and development exploitation（China Patent No.
ZL97112828.6）.It belongs to the replacement kind by innovating the acephatemet that the approach of agricultural chemicals is developed, and is current latest domestic
The toxicity of exploitation is relatively low, efficient, safety organophosphorus insecticide, and it is to rice leaf roller, snout moth's larva, planthopper, leafhopper, Ji
The prevention effect of the insects such as horse, bollworm is better than orthene, suitable with acephatemet.Shown in structural formula following (II).
。
In prior art, China is used for the agricultural chemicals of rice seedling and is mainly single pest control or single controlling disease, can
Pest control simultaneously and the product development of disease are little.Therefore, the insecticidal and bactericidal composition of exploitation preventing and treating rice seedling pest and disease damage,
For the agriculture large-scale development of propulsion has positive effect.
The content of the invention
It is an object of the invention to provide it is a kind of efficiently, low toxicity and can effectively prevent and treat the pesticide-germicide of rice seedling pest and disease damage
Composition, solution is repeated several times dispenser and makes troubles to user in plant disease and the insect pest same period when occurring, and repeats to apply
The adverse effects such as the poisoning that medicine is caused, in particular for rice-stem borer, rice sheath blight disease, rice blast.
To solve the above problems, the technical solution adopted in the present invention is：
A kind of insecticidal and bactericidal composition, containing two kinds of active components, the first active component is bactericide fluorobenzene ether amide, second
