What pests can be controlled by larvaluramide? The scope of use of chloramectin larvaura and what ki

Chlorpyramide, such as Chlorurea 1 and Chloruramide 3. The pure product is white crystal. It is relatively stable to light and heat, and is easy to decompose when exposed to alkali and strong acid.

It is more stable when stored at room temperature. It is a non-toxic pesticide and relatively safe against natural enemies. However, the insecticidal effect is slower and the chemical properties are less stable.

The preparation is 25% chlorchloramide suspension. Larvaluric urea is a growth regulator of insects. The agent is mainly gastric toxicity, which will make the insect larvae unable to molt normally, causing death.

Because adults do not molt, the agent is ineffective against adults, but sometimes it has a certain sterility effect. Chlorpyramide suspension has a precipitation phenomenon, and it should be diluted with water after shaking it well when using. The pesticide application before the third instar of the larvae has a high control effect.

The control effect of pesticide application in the advanced age of larvae is low, so the dosage should be increased appropriately. In addition, it should be stored in a cool place.

Control leaf-eating pests such as Masson pine caterpillar, dance moth, boat moth, tentacle caterpillar, American white moth, etc. , evenly sprayed with 25% suspension 2000 4000 times, sprayed with aircraft ultra-low volume 450 600ml per hectare. Adding 450 ml of urea will give better results.

To control armyworms, borers, cabbage worms, diamondback moths, cabbage worms and other pests, evenly spray 2000 2500 times of 25% suspension agent. Use 25% suspension agent 2000 3000 times liquid to control peach heartworm, tea inchworm and jujube koji. Diuretics, such as furosemide No. 1 and diuretic No. 3, are pure white crystals.

It is stable to light and heat, and easy to decompose in case of alkali and strong acid. It is stable at room temperature. It is a non-toxic pesticide and is relatively safe against natural predators.

However, the insecticidal effect is slow and the chemical properties are unstable. The preparation is 25% pyrethura suspension. Mellon belongs to the category of insect growth regulators.

The agent is mainly toxic to the stomach and will make the insect larvae unable to molt properly and cause death. Because adults do not molt, they are ineffective against adults, but sometimes they have a certain sterility effect. Clofenamide suspension has precipitation, so it should be shaken well and diluted with water when used.

The larvae have high control efficacy before the third instar. The effect of pesticide application in the old age of larvae is low, and the dosage should be increased appropriately. Also, store in a cool place.

Amamectin chlorpyramide is a compound of methylaminoavermectin benzoate and chlorpyramide, which has a fast effect and a wide insecticidal spectrum, and is mainly suitable for pest control of trees, fruit trees, vegetables and crops. It can effectively kill agricultural pests such as forest boat moth, American white moth, cabbage worm, diamondback moth and so on.

1. The scope of use of chlorpylauron

Chlorpyramide is a benzoyl group, which is easy to decompose when encountering alkali or strong acid, but at room temperature, it is more stable to urea. It is almost harmless to birds and is suitable for comprehensive prevention. So, what are the pesticides included in chlorpyramides? Let's take a look. <>

It can be said that chlorpyramide pesticides include fiproniclon, flubolylurea, flubenzylurea, fluridinurea, pyrethuron, boltaramide, fluoride, etc., which are commonly used by farmers and friends, and the use effect and reputation are very good.

Let's take a look at the characteristics of chlorpyramide pesticides. Chlorpyramide pesticides are benzoyl under urea, and the primary powder is white crystals, which are easy to decompose when encountering alkali or strong acid, and at room temperature, the state is more stable.

1.Chlorpyramide pesticides are less toxic to other organisms. It is almost harmless to insects and forest birds, and is very suitable for integrated control.

2.Wide range of use. It can prevent peach rotten branches, tea black virus, vegetables, cabbage armyworm, etc., and the effect is very good. <>

To prevent loose forest caterpillars, the use of aircraft ultra-low volume spray 450-600ml hectares is very effective.

To prevent pests, such as plant corn bugs and moths, it is sufficient to dilute and spray evenly.

3.Harmless to humans. However, crustaceans such as shrimp and crabs are toxic and can also affect the growth and development of silkworms. Therefore, friends who have seafood farming at home should pay attention to the isolation and storage of such drugs and do not come into contact with shrimp and crabs.

4.These drugs should not be mixed with urea to an alkaline substance to avoid resistance to urea. Because it is a kind of sediment, it should be shaken before use, then a small amount of water is added, water is added to the appropriate concentration, and then stirred and sprayed, when spraying, be sure to be even. <>

5.The drug works quickly. The effect of larvaluride pesticides will gradually become apparent after 3-5 days, during which time it should not be mixed with other insecticides. If the age of the pest, the worse the effect of prevention and **, at this time you can increase the dosage appropriately, and the effect of removing pests has been achieved!

Pyrethuron, fiproniclamide, bolluride, flubenzuron, fluridin, these drugs are good drugs for chlorpyramide, very effective, many farmers and friends are very fond of using it.

Benzoylurea: chlorpyramide, fipronifolon, flubolylurea, flubenzuron, flupyramide, bolthurea, fluorolide, procarmonone, thiazinone (prochlorine, eucarde), hydrazine (worm death, rice man), etc.

All larval urea pesticides are harmful to the growth and development of crustaceans such as shrimp and crabs and silkworms.
