During the agricultural planting process, the most annoying thing for growers is pests. They have a large appetite and strong reproductive ability. Sometimes they cannot kill them all after taking medicine several times. In fact, one of the biggest characteristics of pests is that generational overlap is that the pests in a piece of land include both adults, eggs and young nymphs. It is difficult to kill them all at once. The most effective method is to choose a drug that can kill both insects and eggs, which can enhance the effect of insecticides and reduce the number of times of application. Today, I will introduce to you several drugs that can kill both insects and eggs. Let’s take a look.
, avermectin +triazolophos: It is more effective in preventing cotton cotton bollworms. It is recommended to apply medicine twice during the peak period of the cotton bollworm egg hatching to the low-age larvae stage, and mix water evenly according to the prescribed dosage.
, alkynde mites + bromode mites : It is mainly used to prevent and control citrus tree red spider . It is applied in the early stage of the occurrence of red spider damaging, and has a killing effect on eggs, mites, and adult mites. However, it is more sensitive to the tender branches and leaves of citrus spring shoots, so the medicine liquid should be avoided from drifting on the above crops when applying the medicine.
, high-efficiency cypermethrin + leethrin urinary urinary : It can be used to prevent and control pests such as cabbage beet urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary
, spiral mites + benzyl tin: It has good anti-prevention effect on citrus red spiders, and is active in development stages such as mites, juvenile mites, mites and adult mites. It can also be used to prevent and control harmful mites that are resistant to existing acaricides.
, fluorinuride + high-efficiency cypermethrin : mainly used to prevent and control pests such as rhodopsis , cabbage worms, etc. It can take medicine from the peak period of pest egg hatching to the peak period of 1-2 instar larvae. It can not only inhibit the transmission of pest nerve impulses, but also inhibit the synthesis of chitin during embryonic development in the egg, so that the egg cannot hatch normally.
, pyramidale + pyramidal nitrile : Prevent and control pests such as beet syrup , cotton bollworm, twill syrup twill, diamondback moth, etc., especially spraying during the larval stage of the pest in the younger age, can kill the pest eggs and larvae, and last a long time.
, indenhali + thiamethoxam : It can prevent and control rice borer and rice planthopper . It is best to apply medicine from the peak period of pest egg hatching to the low-age larvae. Pay attention to the uniform spray, has the characteristics of stomach toxicity, contact killing and internal absorption, and is resistant to rainwater erosion, and has no interaction resistance with insecticides such as organophosphorus, pyrethroids and carbamates.
, avermectin+ fluoridine urea : has good anti-activity against cotton bollworms. Apply the medicine during the hatching period of the cotton bollworm eggs or the occurrence period of the young larvae, and pay attention to the uniform spray. It has contact killing, stomach toxin and certain fumigation effects. The hatching of eggs, peeling of larvae and pupae deformity, and the feathering of adults is blocked.
9, imidacloprid +pyramidoether: has good anti-activity for tomato whitefly; it has the characteristics of phenyl ether and nitromethylene insecticides, has contact killing and stomach toxic effects, has quick killing activity on whitefly , and has good egg killing effect.
0, Butyl ether urea + pyramidin : It has good anti-prevention effect on red spiders on various crops. When there are 2-3 red spiders on each leaf, it is the best time to use medicine during the peak period of mites hatching. Pay attention to alternately use with other types of drugs to delay resistance generation. This product is extremely sensitive to a variety of crops and seedlings at high temperatures and is not suitable for use.
1, fluorinuride+ methylaminoavermectin benzoate : It has good anti-preventive effect on the anti-dragon moth moth, and should be sprayed evenly before the peak period of egg hatching to third-instar larvae. Vegetables should be taken up at most twice per season.
2, Zhongdingwei + thiazide : It is mainly used to control rice planthoppers. It applies medicine at the peak of rice planthopper nymphs, and focuses on spraying the middle and lower parts of rice, which has better prevention and control effect.
3, octothion + cyanoparimone : It is effective in preventing worms from cruciferous vegetables and vegetables. It is advisable to apply medicine during the larvae of the pest in the middle age, and pay attention to spraying evenly. It should be noted that crops such as sorghum , cucumber, bean are sensitive to octothion. When applying medicine, avoid the drug liquid drifting on the above crops and causing drug damage. The medicine solution should be used as you want. The appropriate time for the medicine is around the evening to avoid the decomposition of the medicine when the light is strong.
4, thiamethoxam+14, insecticide double : It can be used to prevent and control sugarcane borer, with contact killing, stomach toxin, fumigation and internal absorption activities. The sugarcane borer is given medicine during the peak period of egg laying, and has good efficacy.
5, imidacloprid + pyridesidol: It has good control effect on red spiders on apple trees and aphid . It is applied during the peak period of the red spider egg hatching to the low-age larvae stage; or during the larvae stage of aphid larvae, the pills can be applied again at 7-10 days apart.
