Abstract

The invention discloses a bactericidal composition and a pesticide and application thereof. The bactericidal composition consists of prochloraz and cuppric nonyl phenolsulfonate in the weight ratio of 1:30-30:1, preferably 1:15-15:1. The pesticide consisting of the composition which serves as an active ingredient and auxiliary ingredients which are acceptable in pesticides can be used for preventing and controlling anthracnose of cucumbers, blue mould and penicillium digitatum of oranges, rice false smut and rice blast. Test results prove that the composition and the active ingredients of the pesticide can achieve an obvious synergetic effect, the application amount of each ingredient of the pesticide can be reduced effectively, the pesticide resistance of plants can be delayed, the effective duration is prolonged, the prevention and control application range is extended, and the promotional value is high.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition composed of prochloraz and nonyl copper, as well as corresponding pesticides and their application in the prevention and control of agricultural diseases. Background technique [0002] Rice blast, also known as rice fever, is an important rice disease worldwide, and is listed as the three major diseases of rice together with sheath blight and bacterial blight. The disease is an epidemic disease transmitted by air currents, which poses a great threat to rice production. The degree of damage varies with varieties, cultivation techniques and climatic conditions, and generally reduces production by 10% to 20%. [0003] Rice false smut, also known as false smut, green smut, cereal flower disease, blue powdery mildew, is commonly known as "high-yield fruit", which only occurs on the ear of rice and damages part of the grain. The mycelium blocks formed in the da...
