Won the Brighton (BCPC) World Plant Protection Congress Award on October 16, 2007: The Most Innovative Chemistry Award. This award is awarded to chemical pesticides that have made outstanding contributions to the environment and ecology around the world.
2 Product Effects Editor
Highly
effectively activates the fish nitin receptor in insect cells and binds to it, causing the receptor channel to grow abnormally The time is open, thereby excessively releasing calcium ions in the cells, causing paralysis of the insect's muscles, and finally paralysis and death. Its main effects
are stomach poisoning and contact killing. The pests stop feeding within a few minutes after being exposed to the drug, thereby quickly protecting the crops; then the pests show a loss of vitality and their growth is significantly inhibited. Died within 3 days.
Kangkuan (chlorantraniliprole) is mainly transmitted from bottom to top through the xylem in the plant, so it can be applied in the soil on vegetable crops and rice, thereby transmitting to the stems and leaves; it It has a lasting effect of up to 15 days, has a strong penetrating effect, and is also highly resistant to rain erosion. DuPont found through a large number of tests that Kangkuan has a remarkable control effect on pests such as stem borer, rice leaf roller, diamondback moth, cotton bollworm, cabbage caterpillar, and armyworms. When controlling stem borer and rice leaf-roller on rice, the application period is from the peak egg hatching period to the peak stage of young larvae. The dosage per mu is 10 ml (2 packets), mixed with water on the stems. Spray the leaves evenly, and the water consumption per mu is 30 kg. When using on vegetables, the safety interval is 1 day.
When used correctly, "Kangkuan" (chlorantraniliprole) is safe for humans and animals, and is safe for pollinating insects (bees, etc.), parasitic natural enemies, predatory natural enemies (spiders), fish, shrimp and other aquatic organisms. Low biological toxicity. Note: cannot be used on sericulture.
3 Product Features Edit
1. This product has obtained all certificates for pesticide registration, sales and application, and can be promoted and applied on a large scale. Because the chemical structure of chlorantraniliprole has a new insecticidal principle that no other insecticide has, it can efficiently activate insect nytin (muscle) receptors. Excessive release of calcium ions in the intracellular calcium pool leads to paralysis and death of insects. It has high activity against the larvae of lepidopteran pests, broad insecticidal spectrum, and good long-lasting effect. According to current test results, it is 10-100 times more active against target pests than other products. It can also cause disorder in the mating process of certain lepidopteran insects. Research has proven that it can reduce the number of species of Noctuidae.
The egg-laying rate of pests, due to its biological characteristics of good persistence and resistance to rain erosion, these characteristics are actually permeability, conductivity, chemical stability, high insecticidal activity and cause the pests to stop immediately
< p>The comprehensive expression of feeding and other functions. Therefore, it has a longer and more stable crop protection effect than most other pesticides currently in use.2. This dosage form and content are currently registered for the control of major rice pests. It can quickly protect rice growth, and is especially effective against pests that are already resistant to other rice pesticides, such as rice leaf curlers. Borer borer, stem borer, stem borer and giant borer also have good control effects on rice gall mosquito, rice weevil and rice water weevil.
3. This pesticide is slightly toxic and is very safe for pesticide applicators. It is also very safe for beneficial insects in rice fields, fish and shrimps. The duration of effect can reach more than 15 days, has no residual effect on agricultural products, and has good mixing performance with other pesticides.
4 Application Technology Editor
1. According to the application of the Zhejiang Provincial Plant Protection Department to control rice leaf rollers in rice fields, use 10 ml per mu and spray two barrels with a backpack manual sprayer. , regular spray. After seven days, the insecticidal effect reached 94.2%, and the leaf-preserving effect reached 90.0%; after fourteen days, the insecticidal effect reached 86.0%, and the leaf-preserving effect reached 83.9%. Both are better than the control effect of commonly used 5% fipronil at 40 ml per mu.
2. According to the Sichuan Provincial Drug Inspection Department’s application in the rice borer control test, use 10 ml per mu, spray two barrels with a backpack manual sprayer, and spray conventionally. Twenty days later, the white ear control effect reached 96.1%, the insect-damaged plant control effect reached 98.7%, and the insecticidal effect reached 93.6%. The comprehensive control effect is better than the commonly used control effects of 5% fipronil 40ml per mu and 20% triazophos 140ml.
Comprehensive test demonstrations across the country show that: 1. In the Anhui test, 5 ml of this type of pesticide was poured into a bucket containing 4 liters of water, and then a live goldfish was added. Several hours later, the goldfish was still swimming, indicating that the toxicity to fish was very low and could prove to be safe for aquatic animals. 2. Experimental demonstrations on preventing and controlling rice leaf rollers, stem borers, stem borers, and giant borers on rice in Hubei, Jiangsu, and Shanghai all showed that the control effects were better than those of conventional domestic and imported products. Variety of pesticides, so it has great potential for application in the control of common pests in rice-producing areas in my country.
5 Notes for editing
1.
Due to the strong permeability of this pesticide, the pesticide can penetrate through the epidermal cell layer of the stem and enter the xylem, thus It is transmitted along the xylem to other parts where the pesticide has not been applied. Therefore, in field operations, it is better to use mist or fine spray.
However, when the temperature is high and the evaporation in the field is large, pesticides should be applied before 10 a.m. and after 4 p.m. This will not only reduce the amount of pesticide solution, but also better increase the amount of pesticide solution and permeability of the crops, which is beneficial. Improve
higher prevention and control effects.
2. In order to avoid the development of resistance to this pesticide, it is advisable to use it 2-3 times on one crop or one pest, with an interval of more than 15 days between each time.
3. This pesticide has different dosage forms, contents and applicable crops when it is registered in my country. Users should choose different contents and dosage forms of this pesticide on different crops.
4. Kangkuan cannot be used on mulberry trees.
