What to do with hydroponic Guanyin bamboo red spider

The treatment methods of hydroponic Guanyin bamboo red spider are as follows:

1.Brushing and insect control: Observe the plant, find all the leaves infected with red spiders, boil water with garlic or chili pepper, spray chili water or garlic water on the leaves of the plant and then brush the treatment to remove the eggs and pests attached to the leaves.

2.Pruning insect leaves: If the infection of red mites is already serious and the damage to the leaves is quite serious, use sterilized sharp scissors to cut off the leaves where red spiders grow, and collect the cut leaves and the leaves that have fallen due to insect infestation before, gather them together and burn them to avoid further infection to the plants.

3.Spraying drugs: When the red spider is infected with Guanyin, it is necessary to prepare the agent to kill the red spider as soon as possible, such as mite, dicofol, dimethoate and flower insect net, etc., and spray the agent after dilution, and evenly spray it on the whole plant, and spray it everywhere.

4.Ventilation prevention: After spraying with pesticides, it is necessary to move the plants to a sunny, ventilated and ventilated place to let them breathe more fresh air and avoid air stagnation and poor ventilation, which can breed a large number of spider mites.

Control of spider mites.

For damage, we should pay attention to observation, and when the color of the leaves is abnormal, the back of the leaves should be carefully checked, and the individual leaves are damaged, and the insect leaves can be removed; When more leaves occur, spraying should be done as soon as possible, and commonly used pesticides are caricate, dicofol, and dimethoate.

Flower insect net, quick killing, etc. In 400 ml of water, 4 drops of mitete or quick kill or flower insect net can be dropped into 4 drops (equivalent to 2000 times the liquid medicine), 8 drops can be dropped with dicofol or dimethoate (equivalent to 1000 times the liquid medicine), shake well after adding the medicine, and then spray, the spraying requirements are uniform and thoughtful, especially pay attention to spraying the back of the leaves. When spraying, it is best to move potted flowers outdoors, and if spraying indoors, do not approach food and utensils.

After each use, pour out the excess liquid and wash the sprayer with clean water.

Let's talk about red spiders first, in fact, this is a type of mites; Arachnidae, Ticks, Leaf Mites.

Therefore, to carry out chemical control, targeted drug selection is required;

In fact, dimethoate itself is good, and it has a certain control effect on mites, but it is not a special acaricide; Dimethoate can't kill the eggs of red spiders, red spiders are very fecundive, and they are good at hiding, killing the adults, and the eggs will hatch immediately, so dimethoate is not the first choice;

Mites, dicofol EC, mite-dead wettable powder, 1 8 zitogenol EC can all achieve a relatively ideal effect;

In addition, when spraying, be sure to focus on spraying the back of the leaf, red spider especially likes to hide on the back of the leaf.

There is also prevention is better than cure, when there is no red spider, it is necessary to spray in advance to prevent and control, the better is avermectin, a spray can be used for 2 months without worms, why not use avermectin to kill red spiders? Because avermectin can't kill the eggs of red spiders like dimethoate, but it has a long residual effect, and it is best to prevent adult worms.

Don't deal with it, she's going to die herself.
