Abstract

The invention relates to a bactericidal composition, in particular to a bactericide (thiophonate-methy or prochloraz) containing bromothalonil and a type of imidazole. The results of indoor and field experiments show that the composition has a significant sterilizing effect on anthracnosis, has a co-toxicity coefficient of over 140, has a good effect (over 85 percent) of controlling the anthracnosis, can reduce total use of active components, and simultaneously expands the control spectrum.

Description

technical field [0001] The invention relates to a bactericidal composition and application thereof, especially a bactericidal composition containing bromothalonil. Background technique [0002] Anthracnose is a fungal disease caused by the infection of the fungus of the genus Neptonia. This disease is one of the most common diseases that occurs on crops, and it occurs on fruit trees (citrus, grape, apple, peach, pear, litchi, etc.), melons and vegetables (watermelon, cucumber, bitter gourd, Chinese cabbage, kidney bean, tomato, pepper, etc.), It can occur on Chinese herbal medicines, strawberries, and flowers, and can seriously affect crop yield and growth. For example, citrus anthracnose is a worldwide and serious disease, which can cause defoliation, dead branches, fruit rot and fruit drop. Diseased fruit often rots during storage and transportation, so it is also an important postharvest disease. [0003] At present, carbendazim, thiophanate-methyl, prochloraz, difenoc...
