What pesticides can kill rootless vines?

41% of the grass can be tried, spray type, spray in a ratio of 1:4.

These are the two most commonly used.

1. Glufosinate-ammonium, glufosinate-ammonium is a phosphonic acid herbicide, which can inhibit glutamine synthetase in the nitrogen metabolism pathway of plants, thereby interfering with plant metabolism and causing plant death. It has the characteristics of wide herbicidal spectrum, low toxicity, high activity and good environmental compatibility, and its active effect is slower than that of banned paraquat and better than glyphosate, which is safe and efficient.

Performance after spraying: weeds stop growing within 1 day, leaves appear yellow necrosis after 3 days, plants die after 7 days, and the weed control time can reach 30 days, saving labor and effort.

2. Ethylcarboxycarboxy· Glufosinate-ammonium is a kind of biocidal herbicide composed of ethylcarboxyfluorfen and glufosinate-ammonium compound, ethylcarboxyfluorfen belongs to diphenyl ether herbicides, is a very sensitive to light herbicide, under light conditions, can react with oxygen, generate substances with high toxicity to weeds, quickly kill weeds, mixed with glufosinate-ammonium, can significantly improve the speed of prevention and control of broad-leaved weeds under low temperature conditions, and increase the original effective speed to about 3 days.

Characteristics: Wider herbicidal spectrum, can effectively kill almost all annual broad-leaved weeds and grasses; Faster than glufosinate-ammonium; Low temperature resistance, especially in spring and autumn, the effect is more obvious; It is safer for fruit trees, the herbicide will lose its activity when it comes into contact with the soil, and it is especially safe for fruit trees with shallow roots, and it will not produce any *** for stubble crops.

Glad for your question!

Rootless vines have strong survivability, and are easy to return to green after general herbicide spraying. You can use the following recipes to prevent the effect!

1. Chlorofluoropyroxyacetic acid + glyphosate.

Chlorofluoropyroxyacetic acid has a good effect on the control of rattan weeds, and combined with glyphosate, it can play a good control effect.

2. Dimethyltetrachloride + glyphosate.

Dimethyltetrachloride is a hormone herbicide, which has a good effect on the control of some resistant weeds, and the combination of glyphosate has a more prominent effect.

If soil residues are not a concern, mesulfuron-methyl or cycloazinone may also be used.

Hope mine, helped!

The rootless vine refers to the dodder seed, which belongs to the parasitic vine. When clearing, the vines should be cleaned first, buried in a concentrated and deep place, and burned. For the seeds that fall to the ground, they should be deeply turned, so that the seeds cannot germinate, or lose parasitic life and die after germination.

It can also be prevented and treated with pesticides, such as sodium pentachlorophenol, Myron, Dake grass, promethonyl, dichlorophenylnitrile and other drugs, and the concentration of drugs must be well controlled when using drugs to avoid accidental killing of plants.

Summary. If you use it in front of you, use paraquat, but the roots will not kill. If you can use glyphosate before each crop, glyphosate can be killed by the roots of kudzu. But glyphosate works slowly

What herbicide kills kudzu vine?

Hello, I am Mr. Xiao, I will answer this question for you, I have helped hundreds of people solve problems, I have rich experience in the industry, and I have received many likes. Here I have learned about your question, is sorting out the answer for you, due to the number of people consulting, will reply to you as soon as possible, please be patient for three to five minutes, thank you for your understanding

For kissing, you can choose a herbicide, such as trichloropyrooxyacetic acid (Dow cap irrigation), or you can use Wilber (Sentai) for foliar spraying. [Compare hearts].

If you use it in front of you, use paraquat, but the roots will not kill. If you can use glyphosate before each crop, glyphosate can be killed by the roots of kudzu. But glyphosate works slowly

All of these medicines are fine, but paraquat can't kill the roots

Under normal circumstances, pesticides do not kill dead insects for the following reasons: First, the application of pesticides is not immediate. Grain crop pests are divided into four insect states: eggs, larvae, pupae and nymphs.

The insecticides sold on the market are highly recommended to have a good practical effect on young larvae, and larvae without eggs and larvae beyond the third instar have strong resistance to pesticides. If pesticides are applied at the highly recommended dosage at the egg stage and larval stage above the third instar, the pests cannot be killed.

Second, the application method is wrong. The application methods of insecticides include sprayers, powder spraying, splashing, fumigation, etc. Farmers should apply different pesticide application methods according to the characteristics of different pests, different drugs and preparations, so as to be effective.

If the method is not right, the actual effect is really not good. If the printer nozzle of the medical device is too large, the fine particles sprayed out are too large, and the prevention effect cannot be exceeded.

The third is that the types of drugs used are not feng shui. Pesticides are divided into insecticide, sterilization, rodenticide, hoeing, green plant naphthalene acetic acid, etc., and only insecticides are used to prevent pests. In general, an insecticide is only reasonable for one or a few types of pests.

Some are reasonable for each insect state of a certain type of pest, and some are reasonable for only one insect state. The actual effect of the same pesticide on different pests or different insect states of the same pest is also very different. For example, if the drug to control the A pest is used to control the B pest, or the ovicide is used to control the larvae, the actual effect of the insect control is not easy to idealize, and it is <>

Fourth, pests cause drug resistance. Some pesticides have been used for many years, and pests have become resistant to them, and the highly recommended dosage is no longer satisfactory. For example, pyrethroid pesticides prevent cotton wool diseases and pests, and pests are easy to cause resistance.

Today, stores are thinking about mixing pesticides to slow down the development of pests and insect resistance. Fifth, the quality of the analysis of meteorological forecasts for pests in some areas is not high, and the highly recommended time of taking medicine is not accurate.

The damage of food crop pests in different regions is closely related to the climate, physical geography and other environmental factors during the growth and development of crops across the country. Sixth, there are some pesticides that have product quality problems. Some manufacturers are not strict in the production stage, the product quality is unqualified, fake and shoddy, and the application is poor in pest control under the recommended dosage.

There are even some people who sell fake pesticides, and fake pesticides are naturally ineffective against pests. All in all, the cause of pesticides to kill dead insects is very complicated, involving all aspects, if farmers encounter such a situation, they should seek advice from local flight prevention and agricultural technology extension units, reflect the situation truthfully, find the reason, facilitate immediate rescue, reduce losses. If the quality of pesticides is not very good, you can report it to the local agricultural bureau for a fair solution.

The main reason is that there may be too few pesticides, so they can't kill the insects, and there may be that the quality of the pesticides is not particularly good, so they can't kill the insects.

It may be that the pesticide has deteriorated, it may be that the pesticide has lost its medicinal properties, it may be that it has been left for too long, or it may be that the pesticide does not kill the insect.

Pesticides do not kill dead insects, either because the concentration of pesticides is not enough, or because the insects are resistant.
