Summer and autumn is the high incidence season of various pests, not only the breeding speed is fast, the resistance to drugs is also very strong, many agents due to poor control effect, missed the best control period, so that the crop suffered serious harm. Today Xiaobian will recommend several excellent insecticidal formulas to you, and the prevention and control of pests does not seek people.
1. Excellent formula for the prevention and control of drill heartworms: methylvin fluoramide
Methylvidine fluoroamide is a different mechanism of action of fluorobenzamide and methylamino avermectin benzoate (referred to as methylvidrin salt) scientific compound, the formula has a good systemic conductivity, to touch and gastric toxicity, not only can improve the effect of pest control, expand the control spectrum, but also can effectively delay the production of pest resistance. This product has gastric toxicity and touch killing effect, mainly used to control crop lepidoptera pests such as cabbage green worms, etc., the speed of action, long effectiveness, larvae of all ages have high activity, can quickly and long-lasting protection of crops from harm. In the early stage of pest occurrence, 1% methylvidine fluoroamide suspension can be used 10 to 15 ml/mu, which can knock down the pest in a few minutes, with a fast speed of action and an effective period of more than 20 days. The effect on rice dimorph borer and curl leaf borer, corn borer, pod borer and other drill borers is absolutely first-class.
2. Formula for the prevention and control of mesozoan: spirode furazine
The formula is made of two agents of heliospermum ethyl ester and furanose amine compounded so-called the terminator of the tickworm, in the insect nymph dispersion transfer period, wax powder before the formation of the shell, can be used 22.4% helioethyl ester suspension + 20% furofuranamine soluble granules 4000 times liquid spray, or 20% spirant furofuranamine suspension 2000-3000 times liquid, uniform spray, can penetrate the leaf wax layer to achieve permeation layer transfer, and quickly reach the reverse side of the leaf, upward conduction, can achieve positive and negative death, the leaves, stems, The insecticides in various parts such as bark are killed, the insecticide is more thorough, and the pest base is effectively reduced, and the effectiveness period is about 4 weeks.
3. Formula for the control of green insects: Avi chlorobenzyl
The formula is made of avermectin and chlorhexabenz benzamide two completely different mechanisms of action of the insecticide compound, to contact and gastric toxicity, strong osmotic effect. The agent can quickly penetrate from the front of the leaf to the back of the leaf, kill the pests in various parts, and can control small cabbage moths, beet nocturnal moths, twill moths, cotton bollworms, and other lepidoptera pests, and also has a good preventive effect on rice dimorphite, rice longitudinal leaf borer, cotton cotton bollworm and apple peach small heartworm. At the young age of the larvae, 30 to 50 ml/mu of 6% Avi chlorobenzoyl suspension, mixed with 30 kg of water, can kill the pest within 1 day, and the effective period can reach 20 days.
4. Prevention and control of braceous bugs and green blind bugs formula: fipronol and ethyldosu
It is a kind of insecticide mixed with a new chemical insecticide flufenamitrile and ethyl polybactericide, which acts on the insect nervous system, flufenamidine has a touch killing and systemic effect, ethyl polybactericide has gastric toxicity and touch killing effect, and can be used to control sucking mouth organ and chewing mouth organ pests on a variety of crops at the same time. In particular, it has a special effect on hemiptera pests such as green blind bugs and brace bugs. In the early stage of pest occurrence, 40% filamentopyrifosine water dispersion granules 10 to 14 g/mu, mixed with 30 kg of water evenly sprayed.
5. Formula for the prevention and control of whitefly and whitefly: snail and thiamethoxam
Spirothiasis is an insecticide compounded with ethyl spirospira and thiamethoxam, and is a good hand in the control of whiteflies and whiteflies. With a unique two-way conduction function, it can effectively reach all parts of the plant body, kill a wide spectrum of insects, kill both adults and nymphs, and knock down whiteflies quickly, with an effective period of up to 8 weeks. In the heyday of whitefly and tobacco whitefly, 22% spironoid ethyl ester + 40% thiamethoxam suspension agent can be used 40 ml / mu, or 22% spirophyllone thiamethoxine suspension agent 35 ~ 40 ml / mu, mixed with water 30 kg evenly sprayed.
