[0010] Example 1
[0011] For the gray mold disease that occurred during the strawberry harvesting period, it was prepared according to the ratio of 100kg water added 0.8kg wood vinegar, 10% imitation ginkgo extract emulsifiable concentrate (trade name Lvdi, produced by Shantou Peng Biopharmaceutical Co., Ltd.) Dilute the solution, and then spray the infected strawberry plants in all directions. The spraying time must be selected at dusk, and then spraying again after seven days.

Abstract
The high-temperature and high-humidity weather in the facility greenhouse can easily induce various diseases and insect pests of strawberries. The conventional control method is to spray pesticides. Since strawberry is a berry fruit, the peel is extremely thin, which inevitably results in high pesticide residues when strawberries are on the market. The invention provides a pollution-free medicament for preventing and treating gray mold of strawberry. For the gray mold of strawberry harvesting period, 0.5-2 kg of wood vinegar and 0.1-0.3 kg of ginkgo extract or imitated ginkgo extract are added to 100 kg of water. The ratio is prepared into a diluted solution, and then sprayed on the infected strawberry plants in an all-round way, which can quickly kill the strawberry plant diseases without causing any harmful substance residue, and meets the production needs of green food and organic food standards.
Description
technical field [0001] The invention belongs to the technical field of strawberry cultivation, in particular to a pollution-free medicament for safely preventing and controlling strawberry diseases during strawberry harvesting by spraying wood vinegar prepared at a certain ratio and concentration and ginkgo extract or imitation ginkgo extract dilution. Background technique [0002] At present, strawberry out-of-season production mostly uses greenhouses for facilitative or semi-facilitative cultivation. Due to the mild climate in the facility greenhouse, it is difficult to eliminate pests by relying on cold weather. In addition, the indoor high temperature and high humidity weather can easily induce various diseases and insect pests of strawberries. The conventional control method is to spray pesticides. Once strawberries begin to bear fruit, it is impossible to separate the fruit from the plant when spraying pesticides. In addition, strawberries are berry fruits with extreme...
