A method of using predatory mite as a carrier to carry biocontrol bacteria to control greenhouse diseases and insect pests

A technology of predatory mites and bio-control bacteria, which is applied in the field of biological control of agricultural diseases and insect pests, can solve the problems of affecting the crawling of predatory mites, reducing the control effect of insect-growing bacteria, and the death of predatory mites, so as to reduce contact, improve control efficiency, and promote widespread The effect of spreading

Problems solved by technology

[0003] In the existing method of using predatory mite as a carrier to carry entomogenic bacteria, the packaging bag of predatory mite contains water, predatory mites and entomogenic bacteria. In a short period of time, mycelia may germinate and grow. The germination of entomo-infested bacteria in the packaging bag will reduce the control effect of entomo-infested bacteria. At the same time, if the mycelium grows full of the entire packaging bag, it will also affect the crawling of predatory mites. It may even lead to the death of predatory mites, so there is a hidden danger of affecting the control effect

Embodiment 1

[0014] The preparation of embodiment 1 biocontrol bacteria:

[0015] Produce or purchase bio-control bacteria by yourself, the bio-control bacteria are powder, and put them in a low-temperature drying and refrigerating at a temperature between 1°C and 5°C for later use.

Embodiment 2

[0016] The preparation of embodiment 2 predator mite:

[0017] First produce pure predatory mites or almost no medium, and then divide the produced predatory mites into packaging bottles containing dry vermiculite according to the packaging standards, mix them and put them in low-temperature refrigeration at a temperature between 1 ° C and 5 ° C stand-by.

[0018] Wherein, the production of pure predatory mites refers to the use of spider mites to raise predatory mites on spider mite host plants, and when the predatory mites reach the production demand, the predatory mites can be collected, and the collected predatory mites are pure Predator mite; said predator mite with almost no medium refers to the use of prey to raise and produce predator mite in the feeding medium, and the conventional product is obtained when the production amount of the predator mite reaches the conventional packaging volume, and then these products produced are processed and ready to be produced. Pred...

Embodiment 3

[0019] Mixed packaging of embodiment 3 predator mite and biocontrol bacteria:

[0020] When it is necessary to use predatory mite as a carrier to carry biocontrol bacteria to control greenhouse diseases and insect pests, take out the refrigerated biocontrol bacteria and bottled predatory mites, pack the biocontrol bacteria into predatory mite packaging bottles according to packaging standards, cover tightly and mix well. It is then transported to the release area at a temperature between 1°C and 5°C.

Abstract

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.

Description

technical field [0001] The invention relates to a method for controlling greenhouse diseases and insect pests by using predatory mite as a carrier to carry bio-control bacteria, and belongs to the field of biological control of agricultural diseases and insect pests. Background technique [0002] Predatory mite is an important natural enemy in the control of greenhouse pests, and its crawling with biocontrol bacteria is conducive to the spread of biocontrol bacteria, which is beneficial to the control of greenhouse pests and diseases. [0003] In the existing method of using predatory mite as a carrier to carry entomogenic bacteria, the packaging bag of predatory mite contains water, predatory mites and entomogenic bacteria. In a short period of time, mycelia may germinate and grow. The germination of entomo-infested bacteria in the packaging bag will reduce the control effect of entomo-infested bacteria. At the same time, if the mycelium grows full of the entire packaging b...
