Can chlorfenapyr be used to kill insects with blueberries?

Pyrrol is a new type of pyrrole compound, which acts on the mitochondria of cells in insects, and acts through multifunctional oxidases in insects, mainly inhibiting the conversion of adenosine diphosphate (ADP) to adenosine triphosphate (ATP). Adenosine triphosphate, on the other hand, stores the energy necessary for cells to maintain their vital functions. The drug has stomach poisoning and contact killing effects.

It has strong permeability on the leaf surface, has a certain systemic effect, and has the characteristics of wide insecticidal spectrum, high control effect, long lasting effect and safety. Resistant pests can be controlled.

Control objects Diamondback moth, cabbage worm, beet armyworm, Spodoptera litura, cabbage borer, cabbage aphid, spotted submarine fly, thrips and other vegetable pests.

How to use 30 ml of 10% depletion suspension agent or 30% chlorfenapyr per mu when the instar larval stage or insect population density is low, and 40-50 ml per mu when the insect age is high or the insect population density is large, add water spray. Each stubble can be sprayed up to 2 times, with an interval of about 10 days.

Summary. Strawberry seedlings can be beaten with pyridoxel. Because strawberries are easily attacked by Spodoptera litura.

Spodoptera liturae is a gluttonous pest, and the feeding is more miscellaneous, the strawberry plant is relatively short, after planting, he can quickly eat the young leaves of the strawberry, which seriously affects the normal photosynthesis of the strawberry! Therefore, it is necessary to carry out prevention and control, and generally you can choose: chlorfenapyr, tetrachlorantraniliprole, chlorantraniliprole and other agents for control.

If the sulfur is used for sterilization at the seedling stage, it is not recommended to treat it simply, not only is it not safe and green enough, but it is easy to die seedlings, and the germs and seedlings are killed together! If you want to improve the soil, reducing the harmful bacteria in the soil can be solved by fertilizing the biological bacteria with their own nutrients, which can not only improve the soil and reduce the harmful bacteria in the soil, but also nurture and take root, so that the seedlings can grow well.

Hello, dear, happy to meet for you. Can be used for blueberries. Clothianidin can kill underground pests, such as grubs, needleworms, root maggots, leek maggots and other underground pests, in addition to this, it can also kill thrips, aphids, planthoppers, whiteflies, leafhoppers and other ground pests.

Applicable crops of clothianidin: wheat, corn, rice, cotton, green onions, garlic, watermelon, cucumbers, tomatoes, peppers, peanuts, potatoes, etc.

Hello, does clothianidin in blueberry greenhouses affect bee pollination.

I gave blueberries this medicine some time ago, and I recently bought bees that were put in greenhouses and never pollinated, and the bees didn't come out, and the bees died.

It is not recommended to use it before or during flowering, as it still has a little effect on bee pollination.

How long does it take to use this medicine to put bees.

Is there any solution for this.

The effect lasts for 50 days and can be sprayed with water.

Are your blueberries grown in greenhouses?

If it is planted in a greenhouse, the greenhouse can be warmed appropriately to accelerate the volatilization of the efficacy. But you have to get the front box out in advance.

Yes. I fertilized with this clothianidin in it, and the fertilization time was about two months ago.

That shouldn't be a big deal.

The reason why bees do not come out for pollination 1, the greenhouse temperature is lower than 15 or higher than 30 bees in the temperature of 5-35 out of the nest activities, the most suitable temperature for bees to live is 15-25, but when the temperature is below 10 for a long time, bees reduce or stop out of the nest, the temperature exceeds 30, bees also stop flying activities. 2. The temperature difference between day and night in the shed is not good, and the night drops to below 5, or even to 0, at this time the bees have formed a dormant state in the nest, although the temperature rises to more than 15 the next day, but the bees wake up slowly, and are still inactive. 3. The use of pesticides in greenhouses Greenhouse crops are planted with highly toxic, high residue and high systemic pesticides, if the pesticide residues in the greenhouse exceed the resistance of bees, the bees will not come out of the nest, and even poison and die.

Although the effect of the drug is about 50 days, the answer is that bees are more sensitive to pesticides, and at this time, they can generally pollinate crops by manually pollinating them. Artificial pollination method: Mix pollen and additives in an appropriate proportion, then stir them evenly, and then use a special duster to evenly spray the flowering parts of the crops.

Precautions for the use of pyroxidium are as follows:

1. Watermelon, zucchini, bitter gourd, melon, melon, winter melon, pumpkin, hanging gourd, loofah and other crops are sensitive to pyridonil and are prone to pesticide damage after use.

2. Cruciferous crops (cabbage, radish, rape and other crops) should be used before 10 leaves, which are prone to pesticide damage, so do not use them.

3. Do not use drugs in high temperature time, flowering period, and seedling stage, which is also easy to cause pesticide damage.

4. When pyroxonil is harmed, it is generally an acute pesticide damage (the symptoms of pesticide damage will be manifested within 24 hours after spraying). If there is pesticide damage, it is necessary to use brassinolide + alginic acid or amino acid foliar fertilizer in time to alleviate it.

The main insects killed by pyridoxil are: Spodoptera exigua, Spodoptera litura, diamondback moth, two-point leaf mite, grape leafhopper, apple red spider, etc. It is often used for the prevention and control of agricultural pests, and when you will use pyridonil, you should pay attention to the use of it in accordance with scientific and reasonable methods.

How to use chlorfenapyr:

When the young larval stage or the insect population density is low, use 30 ml of 10% depletion suspension agent or 30% chlorfenapyr per mu to specialize in 30 ml mu, and 40-50 ml per mu when the insect age is high or the insect population density is large, and spray with water. Each stubble can be sprayed more than 2 times, with an interval of about 10 days.

Chlorfenapyr is a low-toxicity pesticide, and it is recommended to use it only twice per vegetable stubble to avoid resistance; The interval on cruciferous vegetables is tentatively set at 14 days, and should be used with caution in cucumbers, lettuce, tobacco, melons and vegetables.

1) Pruning and clearing of plants in winter to eliminate the source of insects overwintering in litter weeds and topsoil.

2) Prevent in advance, spray 40% acetamids after the beginning of spring. Poison (Guoguang Bizhi) emulsifiable concentrate 2000-3000 times liquid for prevention, kill insect eggs, reduce the number of hatched insects.

3) Tips for chemical control of scale insects:

Selection of symptomatic agents: stabbing and sucking oral and limb salutations, systemic agents should be selected, covered with thick scale shells (armor), and highly permeable agents such as 40% acetiniums should be selected. Poison (Guoguang Bizhi) 1500-2000 times liquid spray control, or Guoguang Bizhi 1500-2000 times + emamectin benzoate emulsifiable concentrate (Guoguang Leke) 2000 times mixed liquid prevention and control effect is better.

It is recommended to use it 2 times in a row, with an interval of 7-10 days.

Choose the appropriate medication method:

For those that are low and easy to spray, they can be controlled by spraying; For the control of scale insects in tall trees, you can also use the method of hanging "must treat" or inserting "tree insecticide" into the bottle to prevent and control carefully, and the dosage is adjusted according to the tree species, tree potential, climate and other factors.

4) Biological control: protect and use natural enemy insects, such as red-spotted ladybug, whose adults and larvae can prey on the eggs, nymphs, pupae and adults of this scale; After 6 months, the predation rate can be as high as 78. In addition, there are parasitic flies and predatory mites, among others.

(1) Cut off the coat around the affected area and scrub it with warm soapy water to remove the hard scab and dirt; Wash and disinfect with 1% Xinjieer, apply medicine after drying, wipe with 2% 5% aqueous solution of trichlorfon, wipe with a brush dipped in 60% sodium thiosulfate aqueous solution, and then wipe with 5% hydrochloric acid solution after drying, and apply again once every 2 3 days; Mix with equal amounts of sulfur glycerol or rub with iodine glycerin (3 parts iodine tincture, 7 parts glycerin); Add 1 part of tobacco leaves or tobacco stems, add 20 parts of water, boil for 1 hour, and rub when the temperature is suitable; 1 centipede, 50 grams of sesame oil, 50 grams of borneol, ground into powder and coated on the affected area.

2) Feed 1 pc of 100 insect extermination tablets produced by Jilin Chunhua Veterinary Pharmaceutical Factory to the affected animals; Inject avermectin subcutaneously into the neck every other day, and repeat 1 week later.

3) Insecticide injection, produced by Nanjing Jindun Animal Drug Factory, injected in milligrams per kilogram of body weight.

There are many ways to prevent it, and it is necessary to be strict and serious in order to achieve good results.

1) Medicated baths. Soak all the raccoon dogs in the liquid with 2% 3% trichlorfon aqueous solution for about a minute, and repeat again after 1 week.

2) Keep the farm clean and hygienic. Don't have fluffy flying or piles of droppings; Cages, eating utensils and all other equipment used should be cleaned and disinfected regularly.

Ivermectin tablets or sprays can be used, and ivermectin has an effect on parasites on the body surface, lice, mites, fleas, and ticks.

At the same time as taking medicine, other daily necessities should be cleaned up, the cage should be sprayed, and the equipment should be exposed to the sun.

<> the use of pyroxapyr needs to be noted: pyroxil is sensitive to crops such as watermelon, zucchini, bitter gourd, melon, muskmelon, winter melon, pumpkin, hanging gourd, and loofah; Avoid using drugs at high temperature time, flowering stage, and seedling stage; Due to its toxicity to aquatic organisms, there are potential risks associated with rice applications.
