The spiny sucking pests such as whitefly, Bemisia tabaci, aphid, thrips, etc. have great human and material resources to control because of their fast propagation, long migration distance, fast drug resistance and serious harm. With the increase of the times of drug application, the pests have developed strong resistance to these commonly used pesticides. According to the two pest resistance testing laboratories led by Professor Shen Jinliang of Nanjing Agricultural University, the resistance of whitefly and rice planthopper to imidacloprid is more than 1000 times, that is to say, imidacloprid has no effect on the control of these thorn sucking pests. Today, Xiaobian recommends an excellent insecticide -- furosemide, which is specially used for the treatment of such stinging and sucking pests as resistant whitefly, Bemisia tabaci, aphid and thrips, with good effect and long duration.
Introduction of drugs
Furosemide is the third generation of nicotine insecticide developed by Mitsui company of Japan in 1998. It was listed in Japan in 2002, South Korea and the United States in 2005, EU in 2008 and China in 2014. Furosemide is different from other nicotine insecticides in structure, so it is also different from nicotine insecticides in performance. It is called "furosemide". It has no cross resistance with other nicotine insecticides, and has the functions of contact killing and stomach poisoning. At the same time, it also has the characteristics of good inhaling, high quick acting, high activity, long duration of efficacy, wide insecticidal spectrum, etc., and has excellent control effect on the mouthparts piercing insect, especially for the rice planthopper, Bemisia tabaci, Bemisia albopictus and other insect pests with resistance to imidacloprid. The insecticidal activity was 8 times that of the second generation nicotine and 80 times that of the first generation nicotine.
Main advantages
(1) Broad insecticidal spectrum: furosemide can kill dozens of pests, such as aphids, rice planthoppers, whiteflies, Bemisia tabaci, thrips, stink bugs, leafhoppers, leafhoppers, beetles, mealybugs, leafminers, peach moths, rice borers, Plutella xylostella, cabbage moths, etc., and has high efficiency for health pests such as fleas, cockroaches, termites, houseflies, mosquitoes, etc.
(2) No cross resistance: furosemide has no cross resistance to nicotine pests such as imidacloprid, acetamiprid, thiamethoxam, thiamethoxam, etc., and has a high activity to pests that have developed resistance to imidacloprid, thiamethoxam and acetamiprid.
(3) Good quick effect: furosemide is mainly combined with ache in the body of the pest, which can disturb the nervous system of the pest, cause paralysis of the pest, and kill the pest. After application, furosemide can be quickly absorbed by the roots, stems and leaves of the crop, and transmitted to all parts of the plant to kill the pest quickly. Generally, 30 minutes after application, the pest will be poisoned and will not take any food for 2 hours To kill pests.
(4) Long effective period: after spraying furosemide, it can be quickly absorbed by the roots, stems and leaves of the plant, and transmitted to any part of the plant. It can exist in the plant for a long time to achieve the purpose of killing pests continuously. The effective period is longer than 4-8 weeks.
(5) Strong permeability: furosemide has a very high permeability. After application, it can penetrate from the leaf surface to the back of the leaf well. Under the condition of dry soil (soil moisture is 5%), the granule can still play a stable role in killing insects.
(6) Good compatibility: furosemide can be mixed with Spirulina ethyl, pyraphid, nitenpyram, thiamethoxam, thiazinone, pyrrolidone, acetamiprid and other insecticides to control acanthophos, with significant synergistic effect.
(7) Good safety: furosemide is very safe for crops. Under normal conditions, it will not cause harm. It can be widely used in wheat, rice, cotton, peanut, soybean, tomato, watermelon, eggplant, pepper, cucumber, apple and other crops.
Main dosage forms
Furosemide has the functions of contact killing and stomach toxicity, as well as strong renal permeability and absorption. It can be used in many ways and in many dosage forms. At present, the dosage forms registered and produced in China are: 0.025%, 0.05%, 0.1%, 3% granules, 10%, 30%, 35% soluble agents, 20%, 40%, 50% soluble granules, 10%, 20%, 30% suspension agents, 20%, 25%, 30%, 40%, 50%, 60%, 63%, 70% water dispersible granules.
Suitable crops
Furosemide can be widely used in wheat, corn, cotton, rice, peanut, soybean, cucumber, watermelon, melon, tomato, eggplant, pepper, beans, potatoes, apples, grapes, pears and other crops.
Target of prevention and control
It is mainly used to control aphid, rice planthopper, whitefly, Bemisia tabaci, thrips, mirid bug, green mirid bug, leafhopper, leafminer, beetle, mealybug, scale insect, American leafminer, leafminer, peach moth, rice borer, Plutella xylostella, cabbage worm and other dozens of pests, and has high efficiency for health pests such as flea, cockroach, termite, housefly and mosquito.
Using technology
(1) Soil treatment: before wheat, corn, peanut, soybean and other crops are sown, 1-2kg 3% furosemide granules are used per mu for spreading, furrow or cave application, which can effectively prevent and control the harm of aphid, whitefly, Bemisia tabaci, leafhopper and other pests, and the effective period can be more than 50 days.
(2) When planting cucumber, tomato, capsicum, zucchini, watermelon, strawberry and other crops in greenhouse, 3% furosemide granule 1 is used per mu for hole application, which can effectively prevent and control pests such as whitefly, Bemisia tabaci, aphid and other pests in greenhouse, and can also treat virus diseases simultaneously, with a period of validity of more than 80 days.
(3) Seed dressing with fungicides: before sowing wheat, corn, peanut, potato and other crops, 8% furosemide suspension seed coating agent can be used to mix seeds according to the seed ratio of 1450-2500g / 100kg, which can also effectively prevent and control the harm of aphid, whitefly, Bemisia tabaci and other thorn sucking pests at Seedling stage, as well as underground pests such as grub and needle beetle.
(4) spray control: when cowpea, tomato, capsicum, cucumber, eggplant and other crops are seriously endangered by Bemisia tabaci, whitefly and thrips, they can be effectively controlled by whitefly, furfuroxime water dispersible granule 1000~1500 times, or 1000~1500 spironolactone furfuroxime suspension 1000~1500 times, or 60% endrin and furfuroxime water dispersible granule, 2500~3000 times liquid spray, which can effectively control whitefly. The spread of Bemisia tabaci and thrips.
