Protected-field overwintering tomato disease control method

Abstract

The invention discloses a protected-field overwintering tomato disease control method and belongs to the technical field of tomato disease and pest control. The protected-field overwintering tomato disease control method is prevention-oriented and adopts comprehensive control and alternate use of agricultural chemicals. The technical scheme includes that the method includes: respectively adding water into 60% pyraclostrobin metiram water dispersible granules, 30% kresoxim-methyl boscalid suspending agents, 25% pyraclostrobin emulsion, 18.7% enoyl pyrazole ester water dispersible granules, 50% boscalid water dispersible granules and IDHA Cu for dilution, and spraying the diluted substances step by step. The protected-field overwintering tomato disease control method is widely applied to disease control of protected-field overwintering tomatoes.

Description

technical field [0001] The invention discloses a method for preventing and controlling diseases of overwintering tomatoes in protected areas, belonging to the technical field of tomato diseases and insect pests. Background technique [0002] In the planting of tomatoes in protected areas, due to the influence of the small environment of the facilities, diseases are very easy to occur. In traditional disease prevention and control, vegetable farmers generally focus on treatment but not on prevention, or due to unreasonable selection of pesticides, diseases cannot be prevented. When diseases occur, Do not apply pesticides according to the pharmacology and properties of pesticides, arbitrarily shorten the interval between pesticides, increase the dosage of pesticides and mix pesticides blindly, so that the surface of tomato plants is covered with a thick layer of pesticides, which increases production costs and causes pesticides. Harmful phenomenon is very common, and product...

[0002] In the planting of tomatoes in protected areas, due to the influence of the small environment of the facilities, diseases are very easy to occur. In traditional disease prevention and control, vegetable farmers generally focus on treatment but not on prevention, or due to unreasonable selection of pesticides, diseases cannot be prevented. When diseases occur, Do not apply pesticides according to the pharmacology and properties of pesticides, arbitrarily shorten the interval between pesticides, increase the dosage of pesticides and mix pesticides blindly, so that the surface of tomato plants is covered with a thick layer of pesticides, which increases production costs and causes pesticides. The phenomenon of pollution-free vegetables is very common, and the quality of the products cannot meet the requirements of pollution-free vegetables.
