What is the most effective medicine for peanut spider mites?

If there are red spider mites on peanuts, you can dilute dacarbamectin, imidacloprid or avermectin and spray it on the surface of the plant. After one month, the treatment will be effective. Summer is the peak season for insect pests. The plants should be given sufficient light and water, and the soil should be loosened and weeded regularly. You can alternately spray chlorothalonil and omethoate solution in advance for prevention and control.

Treat peanuts with red spider mites with idarubicin or avermectin

Many people do not know what is the most effective medicine for peanut red spider mites. You can dilute dacarbapenem, imidacloprid or avermectin with clean water in proportion, and focus on spraying the parts of the plants that are infested by pests. Spray once a week, and spray 2 to 3 times in a row to achieve effective treatment results.

Red spider mites are a common pest when growing peanuts. Summer is usually the peak season for pests. Red spider mites feed on the sap of leaves, causing the leaves to turn yellow and curl, affecting the photosynthesis of peanuts. In severe cases, the plants will stop growing and die, so prevention and control should be carried out in advance.

When planting peanuts, ensure that the planting environment has sufficient light. Watering should not be too frequent. Wait until the soil surface is relatively dry before watering. Watering once can enhance the plant's disease resistance. Drainage measures should be taken in advance during the rainy season to enhance the plant's disease resistance.

During the growth period of peanuts, fertilizer can be applied appropriately, and thin fertilizer can be applied frequently to promote plant growth and increase yield. The soil should be loosened and weeded regularly to keep the planting environment clean and tidy. The diluted chlorothalonil and omethoate solution can be sprayed alternately on the plant surface in advance to achieve an effective treatment effect.

What medicine should I use if red spider mites appear on roses?

If red spider mites appear on roses, spray them with 1000 times diluted solution of trichloronate or omethoate.

Red spider mites, also known as short-bearded mites, are pests that specifically harm flower leaves and plants.

Five-needle pine and other trees are also susceptible to damage by red spider mites.

The body of the red spider is the size of a needle tip, dark red or purple, and can only be seen as a small red dot with the naked eye.

The orange-red transparent spherical eggs are seen. Its nymphs often gather on the back of leaves and buds of some flowers, sucking them with their mouths.

The initial symptoms of flowers are that the leaves lose their green color, the leaf edges curl upward, and then wither and fall off.

This causes the flower buds to shrink early and, in severe cases, the plant to die.

Red spider mites have 7-8 generations a year, and they start to cause damage in March and April, with serious damage in June and July.

The plants should be observed and inspected regularly. Red spider mites reproduce very quickly when the temperature is high, the humidity is high, and the ventilation is poor.

It is one of the important reasons for plant death.

Prevention and treatment measures:

(1) Soak citrus peels in 10 times the amount of water for a day and night, filter and spray on the plants to prevent aphids and spider mites.

Watering the soil can prevent nematodes in the soil.

(2) 15 g of washing powder, 15 ml of 20% caustic soda, and 7.5 kg of water. Mix the three and spray. Check after one or two days.

The mortality rate of adult and nymph red spider mites is 94%-98%.

(3) Take 50g of wood ash, add 2500g of water and stir thoroughly, soak for two days and nights, filter, then add 3g of washing powder and mix well before spraying

Spray once a day for three consecutive days, and then spray again for three days every other week to eliminate the second generation of pests and also prevent aphids,

Piercing and sucking pests such as red spiders and scale insects. Putting it into the soil can prevent and control maggots.

(4) Light a mosquito coil and place it in the pot of diseased plants. Then tie the pot tightly with a plastic bag. After about an hour of fumigation,

After that, both eggs and adults can be killed. This is a good method that is both economical and effective. Simple method: spray water on the leaves.

Red spider mites are also called spider mites. The red spider mites that harm roses are mainly common red spider mites, namely two-spotted spider mites.

This pest is widely distributed in my country and causes great harm. The red spider mites start to harm the rose from the lower leaves.

It mainly gathers on the back of leaves in the form of adult mites, nymphs and young mites, weaves webs with leaf fibers and sucks juice.

At first, grayish white spots form on the affected leaves, and then the leaves turn yellow and weak, as if they were dried by fire. When the damage is serious, it causes early leaf fall. Common red spiders are serious damage to multi-web succulent plants in greenhouses. The adult body color of common red spiders varies greatly, including orange-red, rust-red, etc.

The female adult is nearly round with black spots on both sides of the body; the male adult is slender, nearly round at the front and pointed at the back, with 4 pairs of legs. The larvae of the common red spider are colorless when they first hatch, nearly round, and have 3 pairs of legs; after molting once to become nymphs, they are slightly reddish and round, with spots on the sides of the body and 4 pairs of legs.

Common spider mites overwinter as female adults and nymphs in the cracks on the surface of host branches and trunks, in the soil, and at the roots of weeds in the field. They become active in March or April of the second spring; more than 20 generations can occur in a year. When the weather is dry and the temperature is high from May to October, the insect population density increases rapidly. When cutting roses are cultivated in greenhouses, spider mites can occur all year round.

Measures to prevent and control rose red spider mites: First, remove and burn the leaves with gray and white spots in combination with pruning in the early stage.

The second is chemical control. You can choose 1000-1500 times of 20% trichlorodicofol emulsifiable concentrate, 1000-2000 times of Leba wettable powder, 2000-3000 times of 73% cypermethrin emulsifiable concentrate, etc. Spray once every 10-15 days, and spray 2-3 times in a row to achieve better results.
