How do I know how much to use when spraying pesticides? What should I pay attention to?

The common insecticides in plantations are acetamiprid acaricide, granular acaricide, acetamiprid insecticide granular insecticide, some of the effects are acidic or acidic and alkaline drugs, different pest prevention, are used with different insecticides, full of insects, whiteflies, green insects, moths, bud insects, scale insects, elephant insects, whiteflies, bugs including underground pests and diseases need to choose special insecticides, if the plantation is full of insects are selected special type of acaricides can be prevented and eliminated, and acaricides only spray mites, insecticides spray moths, <>

Budworms cannot be killed, and prevention cannot be done. Propyramidamine is a white to milky white crystal powder, insoluble in water, soluble in industrial methanol, toluene and other solvents. The state is stable at room temperature, but the photo-oxygen catalysis is fast.

The drug has high toxicity to humans and animals, and is safe for fish species, honey peak hazardous chemicals, and green plants. Avermectin has contact killing and stomach toxicity effects on pests and mites, and has a certain destructive effect on eggs that are about to be egged, and has no systemic insecticidal effect. It has a strong diffusion effect on the leaves after the sprayer and <>

It can eliminate insect pests under the outer skin and is less harmful to precipitation. It is easy to be sucked in the soil layer, cannot be moved, and is decomposed by microorganisms, and has no cumulative effect in the environment. Type: Chemical fertilizer name, preparation, prevention target, efficacy, characteristics, insecticide, aphidpine, aphidicide, 70, acetamiprid, a variety of bud insects, selective, strong systemic aphicide, medicinal strength, long trifluthrin (time), acetamiprid, heart-eating insects, bud insects and other insect pests, inhibition of mites broad-spectrum, high-efficiency deltamethrin (extermination) 20% acetamiprid, heart-eating insects, buds and other insect pests and mites, broad-spectrum, high-efficiency insecticides, acaricides, strong contact killing efficacy, deltamethrin (dichloricide), acetamiprid, heart-eating insects, budworms and other insect pests, broad-spectrum, High-efficiency fast-acting insecticide, obvious contact killing effect, fenvalerate (pyrethrin extermination, rapid killing buta), 5% acetamiprid, heart-eating insects, budworms and other insect pests, broad-spectrum high-efficiency insecticides, <>

Extremely strong contact killing effect, cis-fenvalerate (Rifleling) 5% acetamiprid, heartworms, budworms and other insect pests are the same as above, and the vitality is higher, some cypermethrin (chlorpermethrin) 10% acetamiprid, heartworms, buds and other insect pests, broad-spectrum and high efficiency, with contact killing, stomach toxicity effect, cis-cypermethrin (cypermethrin) 5% milk heartworms, budworms and other insect pests, broad-spectrum high efficiency, with contact killing, stomach toxicity effect, 1 times higher than cypermethrin (100 trees) 10% acetamiprid heartworm, Leaf roller moths, bud insects, etc., also treat mites with a broad spectrum, and the residual effect is very longThe effect of touching and killing stomach poison is strong, and acetamiprid heartworms, leaf curling moths, bud worms, etc., and the treatment of mites is the same as above. The vitality is a little higher

I think if it's indoors, it's best to spray 1 or 3, otherwise it may affect your body, and if you are indoors, you must open the window for ventilation.

Do not use high-concentration pesticides, pay attention to the appropriate mixing of water, and the proportion must be grasped, do not use high-concentration pesticides, and do not use when the ventilation is not good.

When using pesticides, be sure to pay attention to the dosage and dosage, pesticides are toxins. If used in excess, it is likely to have a great impact on the human body.

Insecticides should be sprayed according to the travel patterns of these insects. After we have chosen the right pesticides, we should use insecticides according to a travel pattern of pests. To give a simple example, if there is a pest that comes out at night, then we will use it during the day, and it will be difficult to have an insecticidal effect.

For some insects, which are more active in the morning during the day, we only use insecticides in the afternoon, so it is not conducive to the effect of insecticides, so we must master the travel rules of insects to spray. Of course, when using insecticides, you should be symptomatic**, insecticides, have different damage effects on different insects, don't choose the wrong one. <>

Many insects that grow vegetables are more active in the afternoon and will be more active in the evening, so choose to spray insecticides in the evening to have the best effect. Spraying in the afternoon is actually to play a role in killing insects for their active and frequent dispatch, after all, these insecticides must be sprayed on these insects or sprayed to their staying points, in order to play a good role in killing. <>

Some insects will stay on the leaves, some will stay in the flowers, and some will stay in the fruits, so spray the insecticide according to the location where they stay. For example, if you eat a leaf worm, you should spray it on the foliage, so that these insects can better come into contact and poison them to death. <>

Another thing to be aware of when spraying pesticides is not to spray them in rainy weather. Rainy days will reduce the effectiveness of the drug, and some will be directly washed away by the rain, resulting in incomplete insecticide or half the effort, so this point should really be noted. After all, we spray insecticides to have a good effect, not to let ourselves be busy in vain, otherwise the effect of spraying insecticides will not be good, and it will be a waste of money and manpower.

1.Pay attention to the climate of recent crops, 2Some rules of life of pests and diseases, 3Overall humidity, 4Heat of the air, 5Points such as the presence and location of pests and diseases.

It is necessary to make all the roots accessible, and when spraying, you should also choose some insecticides that are suitable for the roots, so as not to hurt the previous branches, you should choose some more effective pesticides, and you must wear gloves when spraying.

To choose a safe and pollution-free one, pay attention to the composition of the insecticide, pay attention to the proportion of insecticides, but also pay attention to the spraying time, and be sure to stay away from water sources.

1. Dosage. Insecticides are very effective in eliminating some small pests around us, but we should also be careful not to spray too much when spraying insecticides, which will pollute the environment in the house.

2. Location. When spraying pesticides, it is best to avoid things that will come into contact with our mouths, such as dishes and chopsticks, toothbrushes, etc. Because pesticides are somewhat toxic in trace amounts, if they get into the mouth, it is harmful to our body.

3. Avoid fire. When spraying insecticides, you should mainly avoid open flames, because insecticides are flammable items, so try to avoid open flames when using them to prevent fires.

When we use insecticides, we should wear masks, then seal the food, cups, utensils, etc., and then open the seal of the insecticide, press with the middle finger, and spray out the liquid in the insecticide, pay attention to spraying more in the corners and dark places, which can have a better effect.

After spraying all corners and locations of the room, leave the room immediately to avoid the ingestion of insecticides, and wait for about half an hour until the smell in the stool spike has dissipated before you can re-enter. If dizziness or nausea occurs, it is best to discontinue use immediately.
