Biological control is based on biological pesticides, pollution-free pesticides, specific pesticides, low-toxicity, low-residue pesticides, to replace the current method of applying a large number of chemical pesticides to prevent pests. With the development of economy and improvement of living standards, people are increasingly concerned about their own health and living environment. Traditional chemical prevention and control will be gradually replaced by low-toxicity, low-residue pesticides and biological control, which deserves more attention in flower cultivation. .
Biopesticides generally refer to agents that control pests and diseases with living organisms (mycelium, semi-cystine crystals, insect viruses, etc.). Compared with chemical pesticides, biopesticides have no residue, no pollution, no environmental pollution, and can be specific For related diseases, pest species (ie target). At present, the most commonly used at home and abroad are bacterial pesticides, antibiotics, insect hormones, entomopathogenic nematodes and insect virus pesticides.
First, the prevention and treatment of flower pests and insect pests of biological pesticides to prevent flower ulnar, poison moth, caterpillar, yellow moth, tussah and other moths, can use the following agents:
1. Insect growth regulators (bionic pesticides)
Diflubenzuron series insecticide is a new type of insect growth regulator. Its mechanism of insecticidal action is to inhibit chitin synthesis of insect epidermis. Diflubenzuron is mainly a stomach poison, but it can also invade the insect epidermis. The medicament has the advantages of special action mechanism, good control effect, long residual effect period, low prevention and control cost, resistance to rain shower, insect resistant to drug resistance, flower plant and environmental safety, and the like.
(1) Diflubenzuron No. 1: Diflubenzuron No. 1 is also known as diflubenzuron, enemy killing spirit. It is stable in acidic and neutral media and decomposes in alkaline media. Low toxicity to humans and livestock. Formulations contain 20% diflubenzuron suspension, 25% Trifluralin WP. Diflubenzuron 1's main role is stomach poisoning and contact toxicity, so that when the larvae do not form a new epidermis skin, parasites deformity and death. It has special effects on Lepidoptera pests and is also effective against many pests such as Coleoptera and Diptera. For control of armyworm, yellow thorn moth, hawkmoth, and ulnar gills, dilute about 2000 times with water to spray.
Diflubenzuron 1 has a significant precipitation phenomenon. When used, it must be shaken first and then diluted with water; it cannot be mixed with alkaline pesticides; flowers cannot be used when there are mulberry gardens nearby.
(2) Diflubenzuron 3: Also known as Suurea 1 or Diflubenzuron. Pure product is white crystal. The performance of light and heat is relatively stable, and the alkali and strong acid are easily decomposed. Stored at room temperature is relatively stable. It is a non-toxic pesticide and is safe to natural enemies. The formulation was a 25% diflubenzuron suspension.
Diflubenzuron 3 is an insect growth regulator. The agent is mainly stomach poisoning, but also some insect larvae can not immediately molt and die immediately. The larvae no longer take food after taking the medicine. Generally, the larvae begin to be disabled within 3 days after spraying and reach a peak of disability after 5 days. Since the adult does not molt, the agent is not effective for adults. Diflubenzuron 3 has special effects on Lepidoptera pests. For the control of pests such as big moths, ulnar catfish, and yellow thorn moths, 25% diflubenzuron can be used for spraying from 2000 to 2500 times. The use of diflubenzuron 3 dilute water 800 to 1000 times spray control leaf miner and other effects are very good. Diflubenzuron No. 3 suspension has a precipitation phenomenon. When used, it should be shaken and diluted with water. Before the third instar larvae, the application of pesticides has a high control effect. In the larvae, the application efficiency is low, so the dosage should be increased. In addition, it should be stored in a cool place.
The stainless steel mesh is made of metal wires such as 302, 304, 304L, 316, 316L, 310, 310s, etc. The surface is smooth, rust-free, corrosion-resistant, non-toxic, hygienic and environmentally friendly. Uses: hospitals, pasta, meat barbecue, life flower baskets, fruit basket series mainly stainless steel wire mesh, using electropolishing technology for surface treatment, the surface is bright as a mirror.
Stainless steel is heat resistant, acid resistant, corrosion resistant and wear resistant. Because of these characteristics, stainless steel mesh is widely used in mining, chemical, food, petroleum, pharmaceutical, etc., mainly for gas, liquid filtration and other media separation.
