Description
Technical field
The present invention relates to a kind of fungicide mixture, specifically a kind of Pesticidal composition containing Pencycuron and jingganmycin.
Background technology
Pencycuron, chemical name:1- (4- chlorobenzyls) -1- cyclopenta -3- phenylureas, white to off-white color crystalline solid, easily
The organic solvents such as dichloromethane are dissolved in, it is water insoluble.Pencycuron is a kind of ureas antibacterial, and without absorbability, the withered silk bacterium that opposes is drawn
The disease for rising has special role.For Oryza sativa L., Rhizoma Solani tuber osi, vegetable, ornamental plant etc..Rice sheath blight disease is such as prevented and treated, can with 25%
WP foliar spray, per hectare dosage is 0.15-0.25kg.For preventing and treating black scurf of potato, with 1.5% without bleaching powder
Agent 0.5kg/100kg tubers are dressed seed.For the wooden thin film lead fungi of preventing and treating assistant assistant, per hectare is sprayed 2 times with 150-250g effective ingredient,
Just harmful bacteria can be controlled within the specific limits within 10 days after general medication.
Pyrazophos, colourless crystallization is practically insoluble in water, is soluble in benzene, toluene, carbon tetrachloride, trichloroethane, dichloromethane
Deng organic solvent.Pyrazophos are a kind of systemic fungicides.The powdery mildew of vegetable, flowers and fruit tree can be prevented and treated.7 after general medication
It can just control harmful bacteria within the specific limits.
The chemical formula of jingganmycin is C20H35O13N, it is the antibiotic that a kind of actinomycetes produce, and belongs to low toxicity antibacterial,
With stronger absorbability, easily absorbed and rapid conduction in it by somatic cells, disturb and suppress somatic cells growth and send out
Educate.It is mainly used in rice sheath blight disease, it can also be used to which rice green smut, corn northern and southern leaf blight and vegetable and Cotton Gossypii, beans etc. make
The preventing and treating of thing disease.For many years large-scale field fully shows the environment-friendly type of its " preventive effect is high, without poisoning, pollution-free " using result
It is the characteristics of pesticide, deep to be welcome by users at home and abroad.Banded sclerotial blight typically in Oryza sativa L. Feng Hanghou to heading early stage or contains the initial stage of sending out, every time
The jingganmycin 10-15g of per mu of use 5%, is watered 75-100 kilogram, and pin is watered the spraying of rice middle and lower part or sprinkles and pours, interval 7-15
My god, dispenser 1-3 time；Rice green smut, in Rise's boot period, per mu of water preparation 100-150 milliliter of use 5%, is watered 50-75 kilogram of spray
Mist, can just control harmful bacteria within the specific limits for 5 days after general medication.
The content of the invention
The present invention is directed to the deficiencies in the prior art, there is provided a kind of Pesticidal composition containing Pencycuron and jingganmycin.
To achieve these goals, present invention employs technical scheme below：
