A kind of emulsifiable concentrate preparation of bactericidal composition

Abstract

The invention relates to an emulsifiable concentrate preparation of a bactericidal composition. The emulsifiable concentrate preparation has the beneficial effects that the active ingredients including fenamidone and ningnanmycin in the bactericidal composition do not collide with each other when being mixed with each other; compared with the single ingredient, the composition has synergistic effects and can achieve the effects of expanding the bacterial spectrum and greatly improving the control effects on diseases; the efficacy lasts longer, and the fast-acting property is greatly improved compared with that of the single agent; the emulsifiable concentrate preparation conduces to delaying the drug resistance, is low in residues, is easy to degrade in soil after the lasting period, is low in consumption, is more environment-friendly and meets the requirements of agricultural production; the emulsifiable concentrate preparation is safe to crops; the composition has special control effects on the diseases of the crops, such as agricultural vegetables, cereal crops and fruit trees, especially on downy mildew, epidemic diseases and powdery mildew.

Description

technical field [0001] The invention relates to the technical field of bactericidal compositions, in particular to an emulsifiable concentrate preparation of the bactericidal composition. Background technique [0002] The chemical name of imidazolone: ​​(S)-5-methyl-2-methylthio-5-phenyl-3-anilino-3,5-dihydroimidazol-4-one, the structural formula is , belonging to imidazolinones, white powdery solid, melting point 137°C, density 1.285, vapor pressure 3.4 × 10-7Pa (25°C), solubility in water (20°C): 7.8mg / l. Inhibitors of mitochondrial respiration. It has contact killing, penetrating and systemic activities, and has good protective and therapeutic activities. It can control downy mildew and blight (including early blight and late blight) caused by oomycete pathogens, and has good activity against black spot of fruit trees. [0003] Ningnanmycin is a low-toxic antibiotic fungicide, an innovative biopesticide successfully developed by the Chengdu Institute of Biology, Chine...

Problems solved by technology

[0004] After the above two kinds of drugs are used alone for a long time, it is easy to make the plant pathogens develop drug resistance, resulting in problems such as increased dosage, reduced control effect, and shortened duration of effect. Repeated use of pesticides leads to a decline in the degradation rate of pesticides in the soil , is not conducive to the sustainable development of the environment
