Pymetrozine is a novel pyridine heterocyclic insecticide, which has the characteristics of high efficiency, low toxicity, high selectivity, and environmental friendliness. Pymetrozine is a new type of systemic insecticide, which has special effects on piercing-sucking mouthparts pests such as rice planthopper and aphids. It can specifically block the feeding behavior of insects, so that the medicated pests stop feeding immediately. Although they can still move, they finally die of starvation due to the irreversible anti-feeding effect. This mode of action is a new neuroactive toxicological mechanism. In addition, pymetrozine also has the function of blocking insect transmission of viruses, which is extremely effective in preventing and controlling pests that transmit viruses.
Caraterísticas de Pimetrozina
Pymetrozine is a contact insecticide with high efficiency, low toxicity and high selectivity, and has good systemic activity. In plants, it can be transported in both xylem and phloem; therefore, it can be used as a foliar spray or as a soil treatment. Thanks to its good transporting properties, new shoots and leaves can also be effectively protected after spraying the stems and leaves.
Mechanism of action of pymetrozine
Pymetrozine is a representative of pyridine heterocyclic insecticides with a unique mode of action. Studies have shown that as soon as aphids or planthoppers come into contact with pymetrozine, they will almost immediately produce a stylet blocking effect, stop feeding immediately, and eventually starve to death, and this process is irreversible. Therefore, pymetrozine has an excellent function of blocking insect transmission.
Applications of Pymetrozine
Pymetrozine has a high control effect on aphids, planthoppers, leafhoppers, whiteflies, etc. of crops such as rice, vegetables, cotton, wheat, and fruit trees. The agent has excellent selectivity to homopteran pests, and the selectivity to aphids is better than that of the current best anti-aphid agent – pirimicarb, and it also has good systemic properties.
Nitenpyram belongs to the class of nicotinimide insecticides. It has systemic and osmotic effects. The mechanism of action is to inhibit the activity of insect acetylcholinesterase, act on cholinergic receptors, have nerve blocking effect on the synaptic receptors of the nerve axis of insects, and have control effects on cotton aphids.
The mechanism of action of pymetrozine is as follows: rice planthoppers contact with theInsecticide will produce stylet blocking effect, stop feeding, lose the ability to harm plants, and eventually starve to death.
Pymetrozine can be used for the control of rice planthopper. The classic formula, Nitenpyram and triazinone-type insecticide pymetrozine are powerfully compounded, using new technology to effectively complex and adding various synergistic ingredients. It is an insecticide specially developed for the biological characteristics of aphids, rice planthoppers and other pests.
Pymetrozine can control a variety of pests such as Aphididae, Planthoppers, Whiteflyidae, and Leafhoppers, such as cabbage aphids, cotton aphids, wheat aphids, peach aphids, green leafhoppers, brown planthoppers, brown planthoppers, white-backed planthoppers, sweet potato whitefly and greenhouse whitefly.
How to use pymetrozine
1. Root irrigation: Pymetrozine has good systemic activity. In the plant body, it can be transported in the xylem and the phloem. When planting, use 25% pymetrozine WP 1000 times to irrigate the roots, which can effectively control aphids, planthoppers, whiteflies and other pests. The duration of effect can reach about 50 days.
2. Spraying: To control vegetable aphids, whiteflies, rice planthoppers, leafhoppers and other pests, use 15-20 grams of 50% pymetrozine water-dispersible granules per mu. After the treatment, the pests will die slowly after eating. The average is about 60% in 3 days after the treatment, and it can reach more than 95% in 7 days after the treatment. And the duration of validity is more than 25 days.
