Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of bactericidal composition that contains phenol bacterium ketone and fenoxanil.
Background technology
Phenol bacterium ketone is the botanical fungicide that China has independent intellectual property right, and its chemical name is: the 1-o-hydroxyphenyl butanone, and relative molecular mass: 164.20, biologically active: sterilization.Ginkgo is China's Special plant, is called as the plant living fossil, and strong stress resistance is not endangered by the disease worm, studies have shown that in a large number, and ginkgo contains the agricultural bactericidal material, and thus, China's researcher has been formulated new disinfectant use in agriculture phenol bacterium ketone.The activity that most of diseases that phenol bacterium ketone causes pathomycetes such as Ascomycetes, Basidiomycetes, deuteromycetes and oomycetes subclass have protection, treat and root out can be used for preventing and treating the multiple fungal disease on the crops such as wheat, apple, grape, vegetables, oranges and tangerines, paddy rice.To crop, people, animal and beneficial organism safety, substantially pollution-free to environment.But phenol bacterium ketone is in application process, exists that working concentration is higher, the unit are dosage large, the longevity of residure is shorter, the more high deficiency of use cost, and certain anti-medicine risk is arranged, and is unfavorable for the sustainable development of environment.
Fenoxanil Fenoxanil chemical name: N-(1-itrile group-1,2-dimethyl propyl)-2-(2,4-dichlorophenoxy) propionamide.Fenoxanil belongs to interior absorption sterilization, tool protection and therapeutic action.Fungicidal spectrum is wide, and leaf surface treatment or seed treatment can improve output and the guaranteed quality of crop.To Ascomycetes, Basidiomycetes and comprise Alternaria, Ascochyta, the mould genus of tail spore, Colletotrichum, ball Cuo Pseudomonas, Phoma, Ramularia, Septoria, Venturia partly know disease; Erysiphaceae, Uredinales and some Seedborne pathogen have lasting protection and therapeutic action, and rice blast is had special efficacy.Fenoxanil is to people and animals' low toxicity, Environmental security, and fungicidal spectrum is wide, and preventive effect is remarkable, and the lasting period is permanent.
The plurality of advantages such as phenol bacterium ketone belongs to the pesticide new variety that China has independent intellectual property right, has toxicity low, and Environmental compatibility is better.But in application process, exist that working concentration is higher, the unit are dosage is large, the longevity of residure is shorter, the more high deficiency of use cost, and certain anti-medicine risk arranged, therefore for extending the service life of novel germicide kind, be badly in need of the built agent of developing new product variety, improve bactericidal activity, enlarge fungicidal spectrum.
