Abstract
The invention discloses a germicide composite containing azoxystrobin and propineb as well as a preparation method and application thereof. The germicide composite is characterized by containing azoxystrobin, propineb and other auxiliary agents, wherein the weight ratio of the azoxystrobin to propineb is 1-50:10-95. The germicide composite can be used for disease prevention and control on cereals and fruit trees, melons, vegetables and the like. The composite has wide application scope, low cost and good effect. Indoor efficacy experiments prove that the composite has obvious synergy. In addition, reports on mixing of azoxystrobin and propineb never occurred at home and abroad, therefore, the composite is provided.
Description
Technical field
The present invention relates to a kind of bactericidal composition and uses thereof, especially a kind of is the bactericidal composition and the application thereof of main active with Fluoxastrobin and Propineb.
Background technology
Using chemical agent is the most effectively means of control fungal diseases of plants.But long-term use single chemical bactericide continuously high dose, cause problems such as residual, the environmental pollution of medicament and anti-pesticide resistance fungi development easily.Reasonably chemical bactericide is composite or be mixed and have the expansion fungicidal spectrum, improve control efficiency, prolong the optimum period for applying fertilizer, reduce dosage, reduce poisoning, reduce residual, delay fungi drug resistance and positive characteristics such as drug-fast generation and development, bactericide compounded or to be mixed be one of the effective method the most that addresses the above problem.Exploitation new product bactericide price is constantly soaring, and by contrast, exploitation is efficient with research, low toxicity, low-residual composite be mixed have small investment, the lead time is short and be subjected to domestic and international attention, strengthens the development dynamics one after another.
Fluoxastrobin:
Be a kind of brand-new β methoxy acrylic bactericide, have protection, treatment and root out triple function that the energy that destroys germ by the respiration that suppresses germ is synthetic, suppress spore germination and mycelial growth and suppress to produce spore.Fluoxastrobin has the good crop safety and the Environmental compatibility of highly significant.For obtaining best preventive effect, in the medication of disease initial stage of origination, should fill up the water yield during spraying, the crop surface soup is fully covered.Fluoxastrobin is by Syngenta Co.,Ltd's development product, and it is 25% Fluoxastrobin suspending agent that the preparation Amici reaches, and is mainly used in control fruit tree, vegetable disease, because the cost height uses not extensive.
Propineb:
It is a kind of wide spectrum; quick-acting protective fungicides. the safe and sound life of other titles. preparation: 70% Wettable propineb powder. physicochemical property: 70% Wettable propineb powder is a cream-coloured powder. have special smell; density 0.28; pH5.2; suspension stability is greater than 75%; the moistening time was less than 120 seconds; water content is less than 2.5%; storage at normal temperature stability is more than 2 years. toxicity: by Chinese pesticide toxicity grading criteria; Propineb belongs to the low toxicity bactericide. and nontoxic to honeybee. mechanism of action: the bactericidal mechanism of Propineb is for suppressing the oxidation of pyruvic acid in the cause of disease thalline. and Propineb is a kind of quick-acting; the longevity of residure is long; the protective fungicide of wide spectrum; to vegetables; tobacco; the morning of downy mildew of crops such as lupulus and tomato and potato; late blight all has good protective action, and to powdery mildew; the germ disease of rust and Botrytis also has certain inhibitory action. under recommended dose to crop safety.
Summary of the invention
The present invention be directed to the problems referred to above a bactericidal composition that contains Fluoxastrobin and Propineb applied widely, that cost is low, effective is provided.
A further object of the invention provides the purposes of this bactericidal composition.
Measure of the present invention realizes by following measures.
A kind of bactericidal composition, it contains Fluoxastrobin and Propineb, and wherein the weight ratio of Fluoxastrobin and Propineb is 1～50: 10～95.
