Imidacloprid, acetamiprid, and thiamethoxam can be used together to treat rice disease and yellow le

1. Yellow leaves caused by white leaf blight: dark green spots first appear on the tip of the leaf or the edge of the leaf after being damaged, and then turn into long yellow lesions, and the diseased part and healthy part are obvious. The leaves were cut off, sandwiched between two pieces of glass, and water was dripped on them, and a smoky bacterium gushed out.

2. Yellow leaf disease of rice induced by yellow dwarf disease: first from the parietal leaf and its lower 1-2 leaves, expand upward and downward, and then gradually develop to the whole leaf yellowing, or become mottled flower leaves, the plant dwarf shrinks and the internodes are short, the grass leaves droop and flatten, there are many black roots, few new roots, and often roll up and die of yellow wilt.

3. Rice physiological premature aging yellow leaf disease: spread from bottom to top, the diseased leaves are mostly orange-yellow, with metallic luster, and occur in patches or all fields. There are no lesions on the yellow leaves, and there are no bacterial pus.

4. Rice yellow leaf disease caused by fertilizer: improper application of ammonium carbonate, ammonia, pesticides, etc., will cause poisoning, resulting in pieces of rice leaves smoked into bright yellow or golden yellow, and sometimes there are scorching spots on the yellow leaves.

What medicine is used for rice yellow leaf disease.

As mentioned earlier, there are many causes of yellow leaves in rice, and the cause needs to be found before the right medicine can be prescribed

1. Rice leaves are infected with rice leaf blight and other diseases, and the leaf tips and leaf margins are yellow, and 22 grams of 75% wettable powder can be used per mu at the beginning of the disease, mixed with 30 50 kg of water, and foliar spray.

Not only this disease, but other bacterial diseases can also cause yellow leaves of rice, such as yellow dwarf disease and blight, which need to be applied according to the specific disease.

2. Lack of elements in the growth process of rice usually leads to yellowing of leaves.

For example, if rice lacks potassium fertilizer, brown spot and red spot often occur, and most of them turn from yellow to brown at the tips and edges of old leaves from the middle of rice tillering to the heading period, and irregular brown spots occur.

Magnesium deficiency begins with a greenish fading of the veins between the tips and edges of the leaf, and then from pale to yellow. Rice is deficient in sulfur, and the main characteristics are green loss and yellowing. The solution is to apply potassium sulphate and magnesium sulphate through foliar sprays.

3. If the leaves of rice are yellow due to pesticide damage, the plant growth regulator brassinolide, gibberellin or attractin foliar spray can be used to alleviate the pesticide damage, repair the wound of rice by pesticides and fertilizers, and restore the normal growth of rice.

4. The leaf tip of rice is harmed by thrips, planthoppers, and ant borers, resulting in yellowing or yellow wilting. 25 30 grams of 25% thiazinone powder can be used per mu, mixed with 50 kg of water for foliar spray.

There is more than one disease that causes rice yellowing, such as sexual base rot, leaf blight, standing blight, seedling blast, etc., and after infection, there may be yellowing of leaves. An insecticidal composition containing thiamethoxam and acetamiprid, characterized in that the active ingredients are thiamethoxam and acetamiprid, the weight of which accounts for 5 80% of the total weight of the composition, and the weight ratio of thiamethoxam and acetamiprid is (1 10) :(1 10).

The thiamethoxam contained in the preparation of the present invention is the second generation of nicotinic insecticides, which is not easy to produce resistance, and the control effect is better than that of imidacloprid, and can replace imidacloprid to control pests on rice. Moreover, the preparation of the present invention combines thiamethoxam and acetamiprid, and the insecticidal spectrum of expansion has improved the efficacy, and acetamiprid can play a certain acaricidal effect while controlling insect pests. thiamethoxam is the second generation of nicotinoid insecticides after imidacloprid, with the characteristics of high efficiency, low toxicity, broad-spectrum and stomach toxicity, contact killing, and systemic activity, which can effectively block the nerve conduction of pests, and has a good control effect on stinging and suction pests such as aphids, planthoppers, leafhoppers, whiteflies, etc.

The agent can strongly penetrate into the plant tissue, is not easy to photolyze, resistant to rain washing, lasts for a long time, can be used for foliar spray, soil treatment and seed treatment, and has obvious effects on the prevention and control of rice planthoppers.

Yes, but there is no need for this, just use one.

Summary. Answer: Yes thiamethoxam has stomach toxicity, contact killing and systemic activity to pests, mainly used in leaf spraying and soil root irrigation treatment, and has a good control effect on stinging pests such as planthoppers, leafhoppers, aphids and whiteflies.

Imidacloprid also has a variety of effects such as contact killing, stomach toxicity, and systemic absorption, and mainly controls pests such as leaf roller moth, peach aphid, and spotted submarine fly. The two drugs can be mixed, and the effect of pest control will be better after mixing, and the pest species that can be controlled are more extensive.

OK.

None of the three molecules contain phosphorus, so none of them are organophosphorus pesticides.

Imidacloprid is a nicotinoid ultra-efficient insecticide, which has the characteristics of broad-spectrum, high efficiency, low toxicity and low residue, pests are not easy to produce resistance, and are safe for humans, animals, plants and natural enemies, and have multiple effects such as contact killing, stomach toxicity and systemic absorption. When the pest comes into contact with the agent, the normal conduction of the central nervous system is blocked, causing it to paralyze and die. The product has good rapidity, has a high prevention effect 1 day after the drug, and the residual period is about 25 days.

The efficacy is positively correlated with temperature, and the high temperature has a good insecticidal effect. It is mainly used to control stinging and sucking mouthparts pests.

thiamethoxam is a second-generation nicotinoid with a new structure of high-efficiency and low-toxicity insecticides, which has stomach toxicity, contact killing and systemic activity against pests, and is used for foliar spraying and soil root irrigation treatment. It is quickly absorbed after application and transmitted to all parts of the plant, and has a good control effect on stinging and sucking pests such as aphids, planthoppers, leafhoppers, whiteflies, etc.

Isoprocarb is a contact killing and fast-acting pesticide, mainly used for the prevention and control of rice leafhoppers and planthoppers, but the residual effect period is short, generally only 3-5 days. It can treat thrips and leeches at the same time, and is safe for natural enemies of rice planthoppers and spiders. It also has a good control effect on sugarcane planthoppers, potato beetles, and stable flies.

Hello dear I am glad to answer for you, chlorocyanipridant and rice yellow rice sittingling are both insecticides, and the mode of action is different, so they can be used together, but the following points need to be noted: 1Before use, read the instructions of the two pesticides carefully to understand the method of use, applicable crops, dosage and other information to ensure correct use.

2.The dosage of chlorocyanoprid and rice yellow seedling should be used in accordance with the recommendations on the instructions, and should not be used in excess to avoid harm to crops. 3.

The mixing of the two pesticides requires a small area of testing to confirm their compatibility and effectiveness. 4.Attention should be paid to personal safety and environmental protection during use to avoid unnecessary harm to the human body and the environment.

In summary, cyanoimidacloprid and rice yellow rice can be used together, but it is necessary to pay attention to the correct use method and safe use.

Summary. Clothianidin pymetroidine can treat pests such as aphids, leafhoppers, and thrips. Clothianidin is a compound insecticide suitable for rice with a safety interval of 20 days and can only be used up to 3 times per crop.

The snake is a beneficial animal, in fact, there is no need to try to take risks for the possible risks, of course, if he takes the initiative to attack, then use the tools in his hand to drive it away or kill it, if he does not take the initiative to attack, then wait for him to leave quietly, this is the most reasonable solution.
