How do we know that our plants are damaged by spider mites?

On the leaves infected by the spider mite we can see tiny squeezing traces, with a web of webs on the back of the leaves. He's doing a quick job, he can completely destroy the occupied plant. Therefore, it is important to recognize when we are dealing with a spider mite infection.

The spider mite is a dangerous pest because it can completely destroy many hothouse or outdoor crops. Polyphony, more than 280 species of plants on its menu. Its number may rise rapidly over a relatively short period of time, causing unexpected damage. The plants are damaged by sucking, a sign of the tiny, faint suction marks appearing on the leaves, which can blend over time. The back of the leaf is covered by the delicate fabric of the mite, if we find it, we can be sure of the identity of the pest.

WHAT DO YOU NEED TO KNOW ABOUT SPIDER MITES?

There are hundreds of crops and stomachs that live on. Among vegetables, cucumbers, zucchini , watermelons, eggplant, peppers, beans and tomatoes are damaged, among others fruits like strawberries, apples, plums.

Females in the cracks of the greenhouse structure overflow on the surface of the soil, in the open air, in the crusts of the trees or on the hosts, plant residues. It grows in the greenhouse throughout the year as it begins to develop in the open air at 10-15 ° C in spring.

The massive proliferation of spider mites is favored by temperatures above 22 ° C and humidity above 70%. At a temperature below 8 ° C, the egg laying is stopped. The proliferation of mites is supported by the excess of sodium in the ground and the lack of potassium and calcium.

Their terrestrial enemies are predatory mites , predatory bugs, ladybugs, muzzle mosquitoes , predatory thrips, and veils. Often the massive proliferation of spider mites is caused by the use of broad-spectrum insecticides that kill their listed enemies.

HOW TO PROTECT AGAINST MITES?

• With the help of useful predators
• Keeping more resistant plant varieties
• Increase humidity in greenhouses by spraying and spraying to reduce temperature
• With moderate nitrogen fertilization
• In greenhouses with the use of predatory mites
• Modern oil products are also effective
• When acaricides (acaricides) are used, it is important to alternate the active ingredients because common spider mites become very resistant.

PROTECTING OUR HOUSEPLANTS

Since spider mites are not able to withstand moisture, shower them with lukewarm water or spray them with 2-3 days of boiled and cooled water. If you already have measurable damage to the plant, then you should use chemical treatment. If you are anti-chemical, make a nettle or horsetail.

In the case of balcony plants (eg leander) at the  resting place, spray-washing can be effective with a solution of Vectfide R or Vectfide S. This wash should be repeated after two weeks.
