The most feared thing in agricultural production is encountering pests and diseases. The most hateful thing is that there are many types of pests and diseases. Sometimes when they are encountered, they cannot be "treated with the right medicine", which ultimately affects the growth and yield of crops. Today, I will share with you the uses of these 9 pesticides. After understanding them, most pests and diseases can be prevented and controlled.
1. Difenoconazole: The fungal difenoconazole is a broad-spectrum systemic fungicide. After application, it can be quickly absorbed by plants and has a long-lasting effect. It has a preventive and control effect on a variety of pathogenic fungi such as ascomycetes, basidiomycetes, and ascomycetes. It is widely used in crops such as fruit trees and vegetables. It is mainly used to prevent and control diseases such as fat spot yellow spot, black spot, anthrax, sand skin disease, and scab on citrus.
2. Thiamethoxam: Piercing-sucking pests Thiamethoxam, as a second-generation nicotinoid insecticide, has stomach poison, contact killing and systemic activity. It can be used for foliar spraying or soil root irrigation. After application, it is quickly absorbed and transmitted to various parts of the plant. It has good control effects on piercing-sucking pests such as aphids, planthoppers, leafhoppers, whiteflies, etc. It can be used to prevent and control aphids, whiteflies, thrips, scale insects, etc. on citrus.
3. Lambda-Cyhalothrin: Insect and mite killing lambda-cyhalothrin is also called trihalocyhalothrin and kungfu cypermethrin. Its pharmacological characteristics inhibit the conduction of insect nerve axons, have the effects of avoiding, knocking down and poisoning insects, have a broad spectrum of insecticides, high activity, rapid efficacy, and are resistant to rain erosion after spraying. It also has a good inhibitory effect on mites. If used in the early stage of mite occurrence, it can inhibit the increase in the number of mites. Lambda-Cyhalothrin is not inactivated when it comes into contact with soil, and has good effects on underground pests; it has a broad spectrum of insecticides and is effective against most pests; it has good compatibility and can be mixed with most pesticides and fertilizers, and has a good synergistic effect, is safe and environmentally friendly, and does not harm flowers and fruits.
4. Pyraclostrobin: The broad-spectrum fungicide pyraclostrobin has protective and therapeutic effects, and has good penetration and systemic effects. It can be used for various crops such as wheat, peanuts, rice, vegetables, fruit trees, tobacco, tea trees, ornamental plants, lawns, etc. It can prevent and control various diseases such as leaf blight, rust, powdery mildew, downy mildew, blight, anthracnose, scab, brown spot, damping-off caused by ascomycetes, basidiomycetes, deuteromycetes and oomycetes. It has good control effects on cucumber powdery mildew, downy mildew, banana black spot, leaf spot, grape downy mildew, anthracnose, powdery mildew, early blight, late blight, powdery mildew and leaf blight of tomatoes and potatoes.
5. Abamectin: Insecticide and acaricide Abamectin is a highly effective and broad-spectrum antibiotic insecticide and acaricide. It has stomach poison and contact effects on insects and mites, no systemic effect, but has strong permeability on leaves, can kill pests under the leaf epidermis, and has a long residual effect. Mites and insect larvae show paralysis symptoms after contact with the agent, are inactive and do not feed, die after 2 to 4 days, and leave little residue on the surface of the plant, causing little damage to beneficial insects. It can be used to control spider mites, gall mites, tea yellow mites and various resistant aphids in fruit trees, vegetables, grains and other crops, and also has a certain control effect on larvae such as diamondback moth, cabbage worm, leaf miner, etc.
6. Imidacloprid: Imidacloprid is a super-efficient insecticide of nicotine, which has the characteristics of broad spectrum, high efficiency, low toxicity and low residue. Pests are not easy to develop resistance, and it is safe for humans, livestock, plants and natural enemies. It has multiple effects such as contact killing, stomach poison and systemic absorption. After the pests come into contact with the agent, the normal conduction of the central nervous system is blocked, causing paralysis and death. It has a good control effect on aphids, planthoppers, leafhoppers and thrips with piercing and sucking mouthparts, but it is ineffective against nematodes and red spiders, and is harmful to bees. It is forbidden to use it during the flowering period and stop using it 15 to 20 days before harvesting.
7. Acetamiprid: Acetamiprid has contact killing and stomach poison effects on Hemiptera insects, and has strong permeability in plants. It has a wide insecticide spectrum, high activity, low dosage and long lasting effect. It is suitable for the control of Hemiptera pests on fruit trees, vegetables and other crops, causing insect paralysis and eventual death. It can prevent and control various Hemiptera insects, aphids, leafhoppers, whiteflies, scale insects, scale insects, etc. It is also effective against diamondback moths, leafminers, small borers, longhorn beetles, thrips, etc. Granular agents can be used for soil treatment to prevent and control underground pests.
8. Spirotetramat: Piercing-sucking mouthparts pests, red spiders Spirotetramat is a new type of insecticide and acaricide with bidirectional systemic conductivity. It can move upward and downward throughout the plant body to reach the leaves and bark, thereby preventing and controlling pests such as on the inner leaves of lettuce and cabbage, and on the bark of fruit trees. It is highly effective and broad-spectrum, with a long lasting effect, and the effective control period can be up to 8 weeks. It can effectively prevent and control various piercing-sucking mouthparts pests, such as aphids, leafhoppers, scale insects, psyllids, whiteflies, etc. It is relatively safe for important beneficial insects such as ladybugs, aphid flies and parasitic wasps. It is often used to control red spiders and scale insects in citrus.
9. 50% Chloroisobromine cyanuric acid: Fungi, bacteria, viruses Chloroisobromine cyanuric acid is a highly soluble, highly effective, low-toxic, environmentally friendly, and systemic bactericide with a wide spectrum of applications. It can kill a variety of fungal diseases, bacterial diseases, viral diseases, and algae diseases at the same time, and its comprehensive prevention and control effect is very outstanding. In addition, chlorobromoisocyanuric acid is easy to decompose and not easy to leave residue (95% can be decomposed in the soil in one month) and has strong resistance to rain erosion (it can be used before and after rain, and even if it rains 1 hour after use, it will not affect the efficacy of the drug). It also has the advantages of safe use, small dosage, and no need for compounding.
