Description

  The present invention relates to a method for removing spider mites parasitic on the leaves of crops such as strawberries, eggplants, and tomatoes, and a removal tool.

In crops, especially strawberry cultivation, the occurrence of spider mites greatly affects the harvest. If spider mites parasitize the leaves of a strawberry, the leaves lose vitality due to food damage and turn brown, or the fruit becomes poorly colored due to infestation with the fruit, greatly reducing the yield of strawberries.
Conventionally, this type of spider mite has been removed by spraying a miticide or by spraying natural enemy mites that prey on spider mites.
