Benefits of technology

This patented technology helps reduce harmful organisms from cropping plants while maintain good healthy appearance or even improving their overall production efficiency during its entire growing period. Its technical benefits include controlling disease-related issues such as moth borer (Heliothamim) populations that are becoming increasingly important worldwide due to climate change concerns over global food security. Biopesticides have been developed alongside traditional methods like spray drift management programs but they still require large amounts of resources compared to other ways. Therefore, there needs an improvement on these techniques to make them more efficient at reducing damage caused by pest infestation.

Problems solved by technology

This patents describes how farmers want to protect their vegetables from various types of plant injuries caused by certain factors like bacteria called Bacillus subtilis varies among different plants grown worldwide. However, current systems lacked focuses on studying this problem alone due to limitations such as limited understanding of these challengings and potential negative effects associated with chemically controlled agents used during agricultural practical applications.

Embodiment 1

[0029] A method for the whole process of biological control of tobacco diseases and insect pests, comprising the following steps:

[0030] 1) Seedling stage:

[0031] Use predatory mites to control thrips and tomato spotted wilt virus diseases. The control method is to release predatory mites once every 5 days from the next day of sowing, and release them twice at the seedling stage. The release amount is 4 heads / plant. The release method is to feed The "predatory mite-Acaroid mite-wheat bran" mixture of predatory mites, containing 40 predatory mites / g, is spread around the seedbed and on the seedbed;

[0032] Use Heterochromia and Aphidia persica to control aphids and thrips. The control method is to release once every 5 days and alternately release twice at the seedling stage. The release amount is 2 Heterochromia per 100 plants. Braconids are 2 heads / 10 plants;

[0033] Use the inactivated mycelium of Penicillium, 0.5% chitosan, and 0.5% oligosaccharin to prevent and trea...

Embodiment 2

[0050] A method for the whole process of biological control of tobacco diseases and insect pests, comprising the following steps:

[0051] 1) Seedling stage:

[0052] Use predatory mites to control thrips and tomato spotted wilt virus diseases. The control method is to release predatory mites once every 7 days from the next day of sowing, and release 3 times at the seedling stage, and the release amount is 6 heads / plant. The release method is to feed The "predatory mite-Acaroid mite-wheat bran" mixture of predatory mites, containing 60 predatory mites / g, is spread around the seedbed and on the seedbed;

[0053] Use Heterochromia and Aphidia persicae to control aphids and thrips. The control method is to release once every 7 days, and release 4 times alternately at the seedling stage. The release amount is 3 Heterochromia per 100 plants. Braconids are 3 heads / 10 plants;

[0054] Use Penicillium inactivated mycelium, 0.5% chitosan, and 2% amino-oligosaccharides to prevent and ...

Embodiment 3

[0068] A method for the whole process of biological control of tobacco diseases and insect pests, comprising the following steps:

[0069] 1) Seedling stage:

[0070] Use predatory mites to control thrips and tomato spotted wilt virus diseases. The control method is to release predatory mites once every 6 days from the next day of sowing, and release them twice at the seedling stage. The release amount is 5 heads / plant. The release method is to feed The "predatory mite-Acaroid mite-wheat bran" mixture of predatory mites, containing 50 predatory mites / g, was spread around the seedbed and on the seedbed.

[0071] Use Heterochromia and Aphidia persica to control aphids and thrips. The control method is to release once every 6 days and alternately release 3 times at the seedling stage. The release amount is 2 Heterochromia per 100 plants. Braconids are 3 heads / 10 plants;

[0072] Use the inactivated mycelium of Penicillium, 0.5% chitosan, and 1% oligosaccharin to prevent and tre...

Abstract

The invention discloses a whole-course biological control method of tobacco diseases and insect pests. The method comprises the following steps: 1) in the seedling stage: using predatory mites for controlling thrips and tomato spotted wilf viruses; using harmonia axyridis and aphidius gifuensis for controlling myzus persicae and the thrips; using penicillium to inactivate mycelia, and 0.5% of chitosan and 0.5% to 2% of amino-oligosaccharin for controlling tobacco mosaic diseases; 2) in the field period: using the predatory mites and harmonia axyridis for controlling the thrips, the tomato spotted wilf viruses and the myzus persicae; using sex attractants for controlling prodenia litura adults and helicoverpa assulta adults; using Cahtheconidea furcellata for controlling prodenia litura larvae; using 0.5% of chitosan and 0.5% to 2% of amino-oligosaccharin for controlling the tobacco mosaic diseases; using Holder Burkholderia, and Pythium oligandrum for controlling tobacco black shank, black root rot, root knot nematode diseases and the like. The whole-course biological control method of the tobacco diseases and insect pests disclosed by the invention thoroughly eliminates pollution of chemical pesticides on the environment and tobacco pesticide residues and effectively controls the diseases and insect pests continuously and effectively, and the loss of tobacco quality for the diseases and insect pests is controlled within 5%.
