Microorganism pesticide

a. Bacillus thuringiensis: the dosage form is 10billion-15billion live spore/g wettable powder and 10billion live spore/ml suspending agent. It is mainly used in controlling cotton bollworm, oriental tobacco budworm, diamond back moth, cabbage caterpillar and other Lepidoptera pests. For example, by spraying 150ml-400ml suspending agents per mu in the young larva stage (the water consumption will be 30kg/mu-60kg/mu, the same as below) at more than 30 degrees Celsius, the pesticide effect will be best. Notes are as follows (the same as below): it should not be mixed with systemic organophosphorus insecticide or fungicide and should not be used in silkworm area; it should be stored in the cool dry warehouse at lower than 25 degrees Celsius so as to prevent insolation and dampness.

b. Beauveria bassiana: the dosage form is 8billion live spore/g wettable powder. It will have good control effect on diamond back moth, cabbage caterpillar and other Lepidoptera pests. It can reach good control effect by water spraying 150g-300g drug per mu in the young larva stage.

c. Entobacterin: the dosage form is 10billion live spore/g wettable powder. It is mainly used in preventing aphid, cabbage caterpillar, cotton bollworm and so on. It can be sprayed with water or broadcasted by mixing with 20kg-25kg fine soil 200g-250g per mu.

d. Trichoderma: the dosage form is 200million live spore/g wettable powder (trichoderma SP‍). It can be used in preventing gray mold by water spraying 125g-250g per mu.

e. Pseudomonas: the dosage form is 200million live spore/ml water aqua (bacillus cereus). It can be used in preventing anthracnose by foliar spraying 500-800 times liquid.

f. plutella xylostella granulovirus: the dosage form is 4billion PIB/g wettable powder. It can be used in preventing diamond back moth by water spraying 150g-200g per mu. The notice is as follows (the same as below): it should be stored in the cool dry warehouse at lower than 25 degrees Celsius so as to prevent insolation and dampness.

g. HaNPV: the dosage form is 2billion PIB/ml suspending agents. It can be used in preventing cotton bollworm by mist spraying 50ml-75ml per mu.

h. SLNPV: the dosage form is 1billion PIB/g wettable powder. It can be used in preventing spodoptera litura by water spraying 40g-50g per mu.

Microbial origin biochemical pesticide

a. Abamectin insecticide: the dosage form mainly includes 0.2 percent, 0.5 percent, 0.6 percent, 0.9 percent, 1 percent, 1.8 percent and 2 percent of emulsifiable concentrate as well as 0.1 percent and 0.5 percent of wettable powder. For example, by water spraying 1.8 percent of emulsifiable concentrate 20ml-25ml per mu, it can prevent red spider, aphid, cabbage caterpillar, diamond back moth and other pests. When spraying the drug, it should avoid being absorbed by human body or contacting with skin as well as should not pollute water source and pond.

b. Liuyangmycin:the common dosage form is 10 percent of emulsifiable concentrate. Usually, it will be diluted by 1000-2000 times liquid before mist spraying, thus it will have high control effect on Lepidoptera, coleoptera, homoptera, liriomyza sativae Blanchard and other pests, will have good contact action on various spider mites and will also have certain inhibiting effect on mite eggs. Besides, it has low toxicity to human and livestock and is safe for plant as well as many natural enemy insects.

c. Antioxidant rhzomorph: the dosage form mainly includes 2 percent and 4 percent of water aqua. It can be used in preventing powdery mildew by folia spraying 2 percent of water aqua 300ml-500ml every 15-20 days. The notice is as follows (the same as below): it should not be mixed with alkaline pesticide and should be stored in dry cool place.

d. Jinggangmycin: the dosage form mainly includes 3 percent, 5 percent and 20 percent of wettable powder as well as 3 percent, 5 percent, 10 percent and 20 percent of water aqua. For example, it can be used in preventing banded sclerotial blight by foliar spraying 5 percent water aqua 100ml-130ml per mu.

e. Streptomycin: the dosage form mainly includes 10 percent, 24 percent, 68 percent and 72 percent of agricultural streptomycin sulphate wettable powder. For example, it can be used in preventing soft rot by foliar spraying 72 percent of agricultural streptomycin sulphate wettable powder 15g-20g per mu.

f. Wuyiencin: the dosage form is 1 percent of agricultural astromicin water aqua. It will have good control effect on powdery mildew by foliar spraying 500ml-750ml per mu.

g. Oxytetracycline HCI: the dosage form is 88 percent of wettable powder. It can be used in preventing soft rot by foliar spraying 35g-50g per mu.

h. Fungus polysaccharide: the dosage form is 0.5 percent water aqua (“BingDuNing”). It can be used in preventing virus disease by water spraying 165ml-200ml per mu.

Plant source biochemical pesticide

a. Nicotine: the dosage form is 10 percent of nicotine emulsifiable concentrate. By water spraying 50ml-75ml per mu, it can prevent aphid; by mist spraying 27 percent of saponin nicotine water aqua after diluting by 800 times liquid, it can prevent red spider and beetles; by mist spraying 30 percent of tea saponin nicotine water aqua 75ml-100ml per mu, it can prevent aphid; by mist spraying 0.6 percent of anabasine EC 85ml-100ml per mu, it can prevent cotton bollworm and other pests. The notice is as follows (the same as below): the drug should be evenly sprayed and should not be mixed with strong acid and strong alkali pesticide; it should be kept away from light and should be stored in cool and dry place.

b. Matrine: the dosage form is 0.3 percent of water aqua; by water spraying 65ml-150ml per mu, it can prevent aphid, cabbage caterpillar and leafhopper; by irrigating the root with 1.1 percent of wettable powder 2kg-3kg per mu, it can prevent maggots.

c. Veratramine: the dosage form is 0.5 percent of alcoholic solution soluble concentrate. By water spraying 75ml-100ml per mu, it can prevent aphid, cabbage caterpillar and cotton bollworm.

d. Santonin: the dosage form is 0.65 percent of water aqua. By water spraying 100ml-150ml per mu, it can prevent aphid, cabbage caterpillar and other pests.

e. Celastrus angulatus: the dosage form is 0.3 percent of emulsifiable concentrate. By water spraying 300ml-500ml per mu, it can prevent diamond back moth, cabbage caterpillar and other pests.

f. Toosedarin: the dosage form is 0.23 percent of water aqua. By water spraying 70ml-100ml per mu, it can prevent diamond back moth, cabbage caterpillar and other pests.

g. Divostroside: the dosage form is 0.05 percent of water aqua. By water spraying 40ml-60ml per mu, it can prevent cabbage caterpillar and other pests.
