Method for preventing and curing bacterial fruit blotch disease of melon in solar greenhouse

Abstract

The present invention discloses a method for preventing and curing bacterial fruit blotch of melon in a solar greenhouse. Preventing and curing of bacterial diseases are strengthened after the melon is planted, when freshly born melon grows to 3 to 5 cm, the melon is dipped with 150 to 200 mg / kg of a potassium phosphite aqueous solution for the first time, and within 8 to 10 days after melon dipping for the first time, the melon is dipped with 350 to 450 times of an aqueous solution of 3% of ZhongShengmycin wettable powder for the second time. According to the method for preventing and curingbacterial fruit blotch of the melon in the solar greenhouse, bacterial fruit blotch on melon fruits in the solar greenhouse can be effectively prevented.

Description

Technical field

[0001] The invention relates to a method for preventing and controlling bacterial fruit spot of muskmelon in solar greenhouse, in particular to a method capable of effectively preventing bacterial fruit spot on muskmelon fruit. Background technique

[0002] Bacterial fruit spot disease is an important disease of melon, which occurs all over the country. When the damage is serious, it will have a great impact on the melon and cause huge losses to melon production. The main symptoms of the disease: the fruit is infected, and several dark green to dark green water-stained spots appear on the fruit surface at first, and then quickly expand into large irregular olive-colored water-soaked patches with irregular edges. Continuously expanding, within 7-10 days, the whole fruit surface will be covered except the part that touches the ground.
