What is the good medicine for fighting the little white moth, and what medicine is used to prevent a

<> Xiaobai'e? Is it whitefly? I'll upload a ** You compare, if so, you can consider the following agents to control whitefly, After the larvae of whitefly hatch, they gather on the back of the leaves and young branches to fix the feeding hazards, absorb the leaf sap of the branches and leaves, and secrete flocculent wax silk, which will cause bituminous coal disease in severe cases.

For the control of whitefly, spiralworm ethyl ester plus pyripropyl ether, perchlorothiaparloprid compound or pymetrozine dinotefuran.

Compound bifenthrin.

Dinotefuran compound, aiming at the characteristics of the waxy layer on the white whitefly, the liquid medicine is not easy to contact the insect body, and the drug must be added with silicone additives or mineral oil when the number of insects is large.

So that the agent can penetrate into the insect body and work.

There are several ways to control small white moths:

1.Pharmaceutical prevention and control: 10% imidacloprid microemulsion 10 ml barrel, spiromel ethyl ester 10 ml, dinotefuran suspension, 5% pyridyl ether aqueous 25 ml, BT emulsion 400 times, deltamethrin emulsifiable concentrate 2500 times, 80% dichlorvos emulsifiable concentrate 1000 times, 5% rifling 4000 times liquid and other drugs are used alternately to kill insects and eggs, and the effect is good.

2.Agricultural prevention and control: pay attention to cleaning the countryside, strengthen fertilizer and water management, remove weeds in time, and create an environment that is not conducive to the survival of small white moths.

Control methods of American white moth:

1. Artificial physical control measures:

1) Catch adults, late May to early June, late July to mid-August, is the adult feathering high bee period, organize personnel to catch adults in the early morning or dusk every day.

2) Cutting the net curtain, during the net curtain period of the American white moth, using the habit of the larvae before the third instar of the American white moth to gather in the net curtain to feed, organize personnel to cut the net curtain and destroy it in a centralized manner.

3) Trap pupation of grass, before the old mature larvae of the American white moth pupate, at the point where the trunk is meters from the ground, loosen the straw or straw curtain and tie it up tightly to attract the larvae to pupate, change the straw every 7-9 days, and burn the grass together.

2. Pharmaceutical prevention and control measures:

In the early stage of larval net breakage, spraying control is the best. The agent can choose 3000-5000 times of larvaluramide, pest enemy and 1500 times of 5% cypermethrin. When spraying, it must be uniform and thoughtful, and can not be missed; Pianlin uses a fog machine for smoke control, and the agent can use chrysanthemum emulsifiable concentrate, permethrin emulsifiable concentrate, deltamethrin emulsifiable concentrate, etc.

It can also be used in the larval stage to use biological agents matrine and other drugs for smoke spraying or spray control.

3. Biological control measures:

The old mature larvae of the American white moth were released at the pre-pupal stage and the pupation stage, and the pupa of the American white moth was used to parasitize the pupa of the American white moth.

25% chlorpyramide - indigenous organisms.

25% larvaluride-insecticide is a benzoyl insecticide, which can inhibit the synthesis of chitin in the epidermis of insects, resulting in insects not being able to molt normally, and causing larvae to die of molting disorders. This product is mainly gastric toxicity, and is used in the recommended dose, which has a good anti-smelting effect on cabbage green worms.

Thiamcloprid: When 3% thiamethoprid microcapsule suspension is diluted 1000 times, the 48h control effect on the 4-5 instar larvae of American white moth is achieved, which is more effective than the common control agents emamectin benzoate and larvaluride, and the control effect is more than 2 months.

Bacillus thurturinus or polyhedrovirus insecticides or emamectin benzoate can be used. Fenozide or acitretinamide or insecticidal mono. Flubendiliprole or indoxacarb or Sinochem 9080 and other agents for prevention and control.

If you are satisfied with my service, please give me a review.

Adult insects are trapped, using the American white moth sexual attractant Song Code or an environmentally friendly insect tropism trap. In the period when the adult encounters are occurring, put the trap core into the wild trap, hang the trap in the forest, directly trap the male adult, block the pest mating, reduce the reproduction rate, and achieve the purpose of eliminating the pest. The best time to spray is:

Every year at the beginning of the first generation of larvae forming nets.

OK.

Avermectin 2000 times can be used.

At the initial stage of harm, you can use 10% imidacloprid wettable powder 2000 times, or Uranus 3000 times, or avermectin 2000 times, or 20% chloride 2000 times, or 25% chlorchloride wettable powder 1500 times, or 30% acetamiprid or 10% cover kill 10000 times liquid, and spray with the above pesticides alternately every 5-7 days.

It is also possible that the effect is not obvious, and it is best to use pyrethroid pesticides, which have better effects, such as cypermethrin, cyhalothrin, etc.

Hello, friend, yes, you said that this avermectin can kill the little white moth, but pay attention to the ratio of the amount, I hope it can help you.

There are many kinds of turtles in Ersha Little White Goose, and what you are talking about is just one of them that can kill Little White Goose.

Does avermectin kill small white moths? The one is said to kill the little white moth, but the dosage must be explained to the relevant person.
