BACTERICIDE COMPOSITION FOR PREVENTING AND TREATING
ASPARAGUS OFFICINALIS STEM BLIGHT
The invention relates to a pesticide composition, which takes difenoconazole and propionamidine as effective components and is suitable for preventing and treating
Asparagus officinalis stem blight caused by Phomophilus asparagi.
Asparagus officinalis Linn. belongs to Liliaceae and Asparagus. Asparagus officinalis Linn. has high nutritional value, can moisten lung, relieve cough, eliminate phlegm, and has the functions of inhibiting tumor growth. Asparagus officinalis is known as the "king of vegetables" in the international market. In recent years, with the expansion of asparagus cultivation area, the occurrence of asparagus officinalis stem blight disease has been aggravated year by year, which has seriously affected the yield and quality of asparagus officinalis. However, due to the extensive use of thiophanate-methyl and carbendazim wettable powder for many years, the pathogen appeared strong drug resistance in many areas, which greatly reduced the effect of pesticides. Therefore, it is particularly important to find alternative drugs to control stem blight.
Difenoconazole, commonly known as Difenoconazole in English, is a triazole fungicide. The product name is Cisco and Segao, and the chemical name is cis, trans -3-chloro-4- [4-methyl-2-1H-1,2 4-triazol-1-yImethyl) -1,3-didummy pentane-2-yl) phenyl 4-chlorophenyl ether (cis, inverse ratio is approximately 45:55).
Difenoconazole has a broad bactericidal spectrum, and has a lasting protective arldJ504700 therapeutic effect on ascomycetes, basidiomycetes, semiknowledged diseases including
Alternaria, Ascochyta, Cercospora, Colletotrichum, Cochinococcus, Phoma, Ramularia,
Septoria, and Venturia, powdery mildew, rust, and some species borne pathogens. It also has good effect on grape Anthrax and white rot. Leaf or seed treatment can increase crop yield and ensure quality.
Propamidine, chemical name 1,3-di (4-aminophenoxy) propane, belongs to the aromatic diamine class compounds. Propamidine is an endothermic fungicide that can be absorbed, distributed, and metabolized in plants. It has protective and therapeutic effects and is mainly used to prevent crop gray mold caused by grape spore pathogens.
At present, there have been no reports of the combination of difenoconazole and propamidine, and this combination has novelty.
Through experiments, it was found that the mixture of difenoconazole and propamidine has a synergistic effect on the pathogen of asparagus officinalis stem blight, especially in the ratio range of 20:1 to 1:20, which has a significant synergistic effect on asparagus stem blight. Through certain technical means, it can be formulated as a commonly used dosage form in agriculture.
