Bio-pesticides generally refer to pesticides used to control pests and diseases with living organisms. They have the characteristics of no residue, no pollution, and no pollution to the environment. They can act specifically on related diseases and pest species. At present, bacteria, antibiotics, insect hormones, entomopathogenic nematodes, and insect viruses are the most commonly used at home and abroad.
Prevention of flower leaf pests
First, insect growth regulators. Diflubenzuron series insecticides are new insect growth regulators. Its insecticidal mechanism is the inhibition of chitin synthesis in insect epidermis. Diflubenzuron is mainly a stomach poison, but it can also invade the insect epidermis. The product has the advantages of good control effect, long residual effect period, low prevention and control cost, resistance to rain and shower, pest resistance to drug resistance, flower plant, human and livestock, and environmental safety.
Second, it is a bacterial pesticide - Bt emulsion. The Bt emulsion is a Bacillus thuringiensis microbial pesticide belonging to the Bacillus bacterial insecticide. Its main insecticidal ingredient is a half spore crystal. The drug has now become a major biopesticide widely used in countries throughout the world. The pathogenic mechanism of the Bt emulsion is that the Bt insecticidal toxin causes the lesion of the digestive tract of the pest to die. After the leaf-eating pests eat the leaves with Bt emulsion, they cause paralysis, grazing, unresponsiveness, and diarrhea. After that, the black ring appears in the abdomen and gradually expands to the whole body, eventually causing poisoning. After death, the pests turn black and rot, hang upside down or die on leaves and branches. Bt bacteria have pathogenic and poisonous effects on a variety of Lepidoptera larvae and leafhoppers, such as borers, yellow thorns, and moths, and are mainly used to control larvae of lepidopteran pests.
Third, plant pesticides, including the following four.
1% smoke 100% oil: Multi-element Chinese herbal plant emulsifiable toxin insecticide, also can quickly kill insects that are easy to produce resistance, with good degradation, no residue, safe to use, pollution-free, non-pollution and other characteristics, have a stimulating growth of flowers The role.
Baicao No.1 (0.6% matrine lactone solution): It is prepared by crushing, dissolving, adding additives, and penetrating agents from various plants such as Cinnamomum papua, Sophora alopecuroides, and Chinese herbal medicines. The mechanism of action is based on contact toxicity, supplemented by stomach poisons, and has a promoting effect on flower growth. It can be used to control all kinds of aphids and leaf pests of flowers.
Hundred insecticides (1.2% cannaquinine EC): It is a plant pesticide. The active ingredients are nicotine and matrine. They have stomach poisoning, contact and fumigation effects on insects. Low toxicity to humans and animals, no pollution to the environment, no harm to flowers.
Fruit and vegetable net (0.5% alizarin EC): It is a vegetable pesticide. The drug is highly effective, safe, low-toxic, low-residue, and has no phytotoxicity. At the same time with stomach poisoning, contact and a certain antifeedant effect.
Prevention of flower sucking pests
1. Fungal pesticides, mainly dermatophytes.
The dermatophyte is a new type of fungal biopesticides. The main insecticidal ingredient is an ester-soluble sterol compound. It has low toxicity, rapid knockdown of locusts, and the killing of leafhoppers. It does not harm grasshoppers, ladybugs, etc. The beneficial insects have the effect of promoting the growth of flowers.
Second, antibiotic series pesticides.
Qi Qi Su (1.8%, 0.9%): Qi Qi Su, also known as efford, the active ingredient of the drug abamectin, widely used at home and abroad. It can effectively control a large number of plant-feeding mites and other pests that are insensitive or resistant to common pesticides, such as spider mites, leaf miners, moths, moths, poison moths, hibiscuses, etc. Sucking floral pests. Gastrointestinal and contact toxicity to ticks and other pests. Compared with chemical pesticides, after using the drug, the recovery of predatory and parasitic beneficial insects is fast, which is conducive to ecological balance. The drug is easily decomposed with oxygen, light, etc., leaving no residue, and is beneficial to humans, animals and flower plants.
Liuyangmycin (10% water preparation): An acaricide, a new class of antibiotics.
Huaguangmycin (2.5% powder preparation): A new type of antibiotic acaricide, which does not cause pollution to the environment, has no residue in air and soil, and has a protective effect on beneficial insects.
Third, plant pesticides, mainly Guardian birds (0.5% warthrine alcohol), is a plant pesticide, with the main raw material of veratrine alkaloid solution, aphids on all types of aphids, especially susceptible to resistance Best, it also has a certain effect on leafhoppers.
Tilmicosin Injection or Tilmicosin Oral Solution is indicated for the treatment of respiratory infections in cattle and sheep associated with Mannheimia haemolytica, Pasteurella spp. and other Tilmicosin-susceptible micro-organisms, and for the treatment of ovine mastitis associated with Staphylococcus aureus and Mycoplasma spp. Additional indications include the treatment of interdigital necrobacillosis in cattle (bovine pododermatitis, foul in the foot) and ovine footrot.
