6 most dangerous garden pests
In nature, there is always a struggle for space and food. There are no winners in this fight. Biological equilibrium is simply established when beneficial representatives of the fauna restrain the pace of pest reproduction. And such pests, usually multi-eating representatives of the fauna, are capable of destroying vast areas with vegetable, grain and fruit crops in a day. On cultivated lands, true owners of gardens and kitchen gardens begin to fight such pests in their own ways. In this material, we present to you the six most dangerous pests of garden crops and measures to combat them.
1. Ticks - cosmopolitan omnivorous pests
Among ticks, the most famous and common spider mites (Tetranychidae) Of the 50,000 species, more than 1,250 are found everywhere, including Antarctica. Spider mites are very small arachnids. Males 0.3-0.6 mm, females up to 1.0 mm. The body of the spider mite is rounded, covered with small setae, sometimes microscopic warts. On the head are 2 pairs of eyes, the sucking mouth apparatus. Five-membered legs. The body color of the spider mite is variable and depends on the color of the main host. Most often, ticks have a red, green, brown, yellowish-green, dirty green color.
By piercing the tissue, the spider mite sucks the cellular contents.
Spider Mite Danger Level
Spider mites, occupying the plant, are able to completely destroy it in 3 days. Gluttony of ticks, coupled with the speed of reproduction (from laying to an adult takes 7 days), in optimal environmental conditions cause literally epiphytotic damage to the leaf mass of green plants, which will never recover and must be destroyed.
To protect themselves from the environment, ticks braid their place of residence with a thin web (not all species). They live in colonies under leaves, lumps of earth. Eggs under 5 years of age remain viable.
What crops affect ticks?
All types of ticks belong to the group of dangerous pests of garden and berry and park crops. Pests settle on all plants, including flowering and indoor plants. They are especially attracted to all fruit, strawberries, beans, onions, jasmine, roses. Of the flowering ones, begonia, gladioli, tulips, hyacinths, orchids and others.
External signs of plant damage by ticks
On the leaves of the infected plant (in bright light) spots of yellow color, small holes, silver traces (cobwebs), discoloration of the plant, deformation of the leaf blade are visible. Damage to plants by spider mites is usually epiphytotic.
Tick Control Methods
Preventive, chemical, biological.
To have time to save the affected plants, especially indoor and growing in the open ground, a systematic inspection of the plants is necessary. If suspected of being infected by ticks (especially flowering crops), treat the plants with pyrethrum or biological products Iskra-bio, Akarin, Fitoverm.
In cases of severe damage to horticultural crops by spider mites (30-35 days before harvest), plants can be sprayed with karbofos, celtan, difocol, telly and other contact-intestinal preparations. Colloidal sulfur is used in greenhouses.
