The advantages of Bacillus thuringiensis
(1) The production process of Bacillus thuringiensis meets the environmental requirements, and there is less residue in the field after spraying insecticides.
(2) Bacillus thuringiensis pesticide production cost is low, its production of raw materials from a wide range of sources, are agricultural, by-products, the price is relatively cheap.
(3) The product has a wide insecticidal spectrum and has toxic effects on more than 200 kinds of lepidoptera pests.
(4) Continuous use will form an epidemic area of pests, resulting in the widespread spread of pest pathogens, and achieve the purpose of natural control of insect population density.
(5) The use of Bacillus thuringiensis insecticides is pollution-free to the environment and water sources, harmless to humans and animals, and safe to most natural enemies insects.
(6) Bacillus thuringiensis can be mixed with a variety of other biological agents, insect growth regulators, pyrethroid silkworm toxins, carbamates, organophosphorus pesticides and some fungicides and chemical fertilizers.
(7) The alternate use of pesticides and chemical pesticides can improve the resistance of pests to chemical pesticides.
Usage method
Insecticide Bacillus thuringiensis preparation can be used for spraying, spraying, filling, making granules or poison bait, etc., can also be sprayed by large area aircraft, and can also be mixed with low dose chemical insecticides to improve the control effect. In addition, the dead insects can also be reused, the blackened and rotten insect body will be poisoned by the Bacillus thuringiensis, rubbed in water, and each 50 grams of the insect corpse lotion will be sprayed with 50 to 100 kilograms of water, which has a better control effect on a variety of pests.
(1) Prevention and control of lawn pests: Spray with 10 billion spores /g of bacterial powder 750 g/hm2 diluted with water 2 000 times, or mix 1 500 ~ 3 000 g/hm2 with 52.5 ~ 75 kg of fine sand to make granules and scatter them into grass roots to prevent and control pests that harm the roots.
(2) Prevention and treatment of corn borer: 150 ~ 200 grams of wettable powder per mu, 3 ~ 5 kg of fine sand, mix and scatter in the heart leaf.
(3) Prevention and treatment of cabbage worm, cabbage moth, beet moth, tobacco, tobacco worm: 100 ~ 150 grams of wettable powder per mu, 50 kg of water spray.
(4) Prevention and control of cotton, cotton bollworm, bridge worm, rice, rice leaf roller borer, borer: 100 to 200 grams of wet-able powder per mu, 50 to 70 kilograms of water spray.
(5) Control of fruit trees, trees, pine caterpillars, food worms, inchworms, tea caterpillars, tea inchworms: each mu with wettable powder 150 ~ 200 grams/mu, water 50 kg spray.
