Can dimethoate and beetle squint kill red spider spiders on corn?

Yes, if you spray a hundred insects on the spider, he will die, I have used it, this also works on the spider.

Pesticide control corn irrigation before 3 Jialing granules 30 45kg per mu, 10 15cm away from the corn plant ditch or hole application, depth of about 10cm, irrigation after application. The top application method is to use 40 dimethoate 200 times liquid, loaded into the 16 type sprayer of workers and farmers, the nozzle is wrapped with double-layer gauze, the switch is turned on, and the air is gently pumped to make the liquid medicine droplet, and 10 20 drops per plant are dropped on the corn growth point or upper leaves.

After the corn jointing, the fields where the corn red spider has reached the control index should be fumigated with poisonous sand and the key treatment should be implemented. The method is to use 3 75kg of 25 dichlorvos emulsifiable concentrate per mu, 90 120kg of water, spray and mix it on 750kg of fine sand and sprinkle it into the corn rows in the evening. On the basis of the implementation of the above-mentioned technical measures, it is generally not advisable to directly use insecticide spraying in corn fields for control, but for individual fields that have broken out, 1 8 avermectin 1500 times liquid spray leaves can be used.

Precautions First, pay attention to the safety of humans and animals during the application of pesticides, and apply pesticides after 5 p.m. to the evening in case of hot and bright weather. Second, the sprayer that has been sprayed with herbicides must be thoroughly cleaned before spraying insecticides and disease controls. The third is to administer the water without underground immersion, dry well water and mixed water, pour some water and then pour the medicine, and finally add to the required amount of water, spray thoughtfully.

Killing red spiders depends on what crops and control time, as well as the degree of harm.

On fruit trees, Baume 5° stone sulfur mixture can be used to clear the garden before germination, after germination, pyridoxine foliar spray can be used, and tetramitezine and spirocarbine can be used in the middle stage. In this way, there will be no major harm in the later stage. And you can use phenthiacarb.

In the daily control of pests, bifenthrin, avermectin and other insecticides that also control mites can be used.

Killing acaricides, red spiders belong to the class of mites, and many pesticides to control mites can kill them.

Dimethoate pesticides are suitable for killing insects

Spider mites, aphids, mulberry white scales, thrips, scale insects, mole crickets, mites, leafhoppers, sagittal scales, etc.

The pests that can be killed by dimethoate pesticides are:

Control of pests of stinging and sucking mouthparts, some pests that hide in leaf curling, shrinking or sneaking into leaves, as well as some pests and lepidopteran larvae and beetles that have just burrowed into the stem and dry epidermis, aphids, red spiders, thrips, etc., which develop resistance.

scale insects and whiteflies such as blowing cotton scales, brown soft scales, mulberry white scales, paramecium, sagittal scales, etc.; borrowing pests; Grubs, mole crickets, planthoppers, leafhoppers, scale insects, overwintering aphids, mites, psyllids and scales.

This is a broad-spectrum organophosphate insecticide. It can kill aphids, red spiders and many other pests. Now it's basically restricted.

OK. Dimethoate oxide has a strong contact killing effect on pests and mites, especially for some aphids that have been resistant to dimethoate, with high virulence and can still maintain strong toxicity at low temperatures. It is mainly used to control a variety of banana aphids, red spiders, leaf rollers, Spodoptera litura, flower thrips and webbugs, etc.

Dimethoate also has a strong systemic insecticidal effect, which can be sucked into the human body by the stems and leaves of the plant, and can be transmitted to the part that has not been sprayed to the liquid medicine, so that the pests that harm it are poisoned and die. Therefore, when using dimethoate, the method of coating the stem can be used.

High-efficiency dimethoate can kill red spiders, but the effect is not particularly good.

Spider mites belong to the family Leaf Mites and are a common plant pest. The leaves of the affected plants show gray-yellow spots or patches, and the leaves become yellow, or even fall off.

The spider spider has a strong reproductive ability, and under the conditions of high temperature and drought, it reproduces rapidly and causes serious harm. When a plant is found to have spider mites, it should be sprayed as soon as possible for control. Commonly used agents include mite threat, dicofol EC, mite-killing net wettable powder, zitogenol EC, etc., which can achieve ideal control effects.

When spraying, it is best to move the potted flowers outdoors, prepare the agent according to the instructions for use, and spray the requirements evenly, especially pay attention to the back of the leaf should also be sprayed.

Yes, but it doesn't work well, and resistance developed almost 20 years ago. To kill red spiders, professional acaricides are required, such as: avermectin, pyridafen, and mite.

Well, the method of medicine versus water.

Avermectin, pyridoxin and other red spiders can be used to control red spiders.

Corn red spiders, with dicosulfone control.

To control corn red spider, you can use agricultural control, that is, remove weeds at the edge of the field, and avoid intercropping with soybeans, you can also choose avermectin, pyridoxine emulsifiable concentrate for spray control, every 10 days of medication, 2 to 3 times in a row are effective.

Corn red spider can be controlled with avermectin.

Aphids, at low temperature, it is recommended to spray imidacloprid plus bimethrin once, when the temperature is high, use acetamiprid or enthomidamin plus pymetrozine spray treatment once, you can also use furidoxamide or dimidamitrine, alternately, there are also imidacloprid root irrigation, it is better to fight in the later stage.

Red spider can be used with alkyne mite or butafenoxidel or bifenazide or ethoxazole or spirodifenoxil or azole dixilate, pyridafen or thiofenone or tetradizine, etc.

Tell you a secret recipe: use the emulsifier used by the lathe to dilute it with water for 1:1000, and you can kill the red spider cleanly.

Dicofol, dimethoate, dimethoate, dimethoate, or scale mites can be used to kill spider mites. Dicosulfone can kill the eggs of red spider mites.

[Dicofol] or [Gram mite] can be used.
