The invention relates to a
greenhouse disease-and-
insect-pest controlling method using
predation mites as a carrier to carry bio-control
bacteria. The method includes four parts, namely, bio-control bacterium preparation,
predation mite preparation, mixed packaging of the
predation mites and the bio-control
bacteria,
greenhouse disease-and-
insect-pest controlling using the predation mites as the carrier to carry the bio-control
bacteria. In the method, the bio-control bacteria and the predation mites are required to be stored separately, pure or almost free-of-any-medium predation mites are selected,
vermiculite used for packaging media must go through
drying treatment, a refrigerated storage temperature is between 1-5 DEG C, when the predation mites are needed to be used as the carrier to carry the bio-control bacteria to control
greenhouse diseases and
insect pest, the predation mites and the bio-control bacteria are mixed, and a broadcast
sowing method is adopted as a releasing method for releasing the predation mites and the bio-control bacteria. By the aid of the greenhouse
disease-and-insect-pest controlling method, a potential safety
hazard that the bio-control bacteria germinate in a packaging bag can be avoided, and more than 10% prevention effect can be further enhanced.
