Luxury strawberry shrubs grow to dwarfishsizes and are characterized by oppression, the first leaves grow to normal size and literally after some time together with the rest they become twisted and wrinkled, on the underside of the leaf plates there is a silvery coating - these are the external signs of the presence on the garden plant of a dangerous pest called a "strawberry mite".
Description of the strawberry mite
The pest of strawberry plantations is common inall regions of cultivation of this garden culture and is characterized by very small sizes (from 0.1 to 0.2 mm), so you can see the insect only with the help of a magnifying device.
Parasitic activity
Typically, the laying of small elliptical eggs of the female produces on both sides of a young leaf that has not yet opened. At a comfortable temperature of +19 ... +25 aboutWith the development of one generation of garden pests lasts from 2 to 9 weeks.
Больше всего растения заражаются таким вредителем in the middle of summer, when there is not enough moisture in the soil. It was at this time that insects feed with particular intensity, so the symptoms of damage to the bushes are most pronounced. With the onset of cold weather, the rate of development of the berry pest decreases; egg laying stops at temperatures below +13 aboutWITH.By the end of autumn, the males die, and the females winter over the stipules, at the base of the plants, sometimes waiting for the cold between the folded plates of young leaves. If strawberry mite is found on strawberries, how to deal with such a pest? We will look at this later.
The effects of tick activity
In all phases of development, the strawberry mite lives inrudiments of flowers and on young, only revealing leaves of strawberries; moves freely within the bush. The consequences of the vital activity of a small pest are very destructive for plants: the yield of infected strawberries drops sharply, the leaves become yellowish-oily, shrink and die.
The fight against berry pest should beginimmediately, since its discovery. In early spring, you need to collect all the remnants of vegetation from the beds, because pests can winter in them. Then burn the collected mass or put into the compost, after having been disinfected. Also on each shrub of the plant it is recommended to carefully pour to half a liter hot (about 80 aboutC) water, then spud, feed and water.
Tick against tick
Избавиться от вредителя достаточно трудно по reason of inaccessibility to the places of his settlement. The control of strawberry mite can be carried out by an alternative method, which consists in releasing its natural enemy, the neoseyulyus cucumeris mite, onto damaged bushes.
Strawberry mite: control measures
Effective measure to combat gardenThe pest, in which you can get rid of 90 to 95% of its quantity, is mowing the green mass immediately after harvesting. Pre-site is required to weed from the weeds, fertilize with fertilizers and water. With the timing of such a procedure should not be late, since the plant before the onset of cold weather is required to have time to increase the leaf crown. Then you need to make a three-time, with a weekly interval, spraying the cleaned area with biopesticides "Akarin" or "Fitoverm" at the rate of 20 ml of money per bucket of water. Effective use of chemical drugs "Actellic" (15 ml per 10 liters of water) or "Fufanon" (30 ml per 10 liters of water). Treatment should be carried out twice within 10-14 days. Chemicals are recommended to alternate, as the tick quickly becomes accustomed to pesticides.
Sometimes the result is disappointing.
Due to finding most of the peststhe bases of the strawberry bush on the half-opened or still undisclosed leaflets, the treatment with even highly effective preparations may be disappointing with an unsatisfactory result. This is due to the fact that it is rather difficult to deliver the working solution to the hard-to-reach habitats of the tick due to the obstructive thick leaf cover.
Before the beginning of the growing season with significanttick infestation should spray all berry plantations with 3% Bordeaux mixture. An effective measure in the fight against insects is the treatment of cultivated plantings with a 70% solution of colloidal sulfur, carried out in the period of foliage regrowth, before flowering and after the formation of fruits.
Folk methods
In the spring, with the growth of the first leaves, in the periodbookmark buds and twice after harvest, you can destroy the garden pest infusion of onion peel. To prepare it, 200 grams of dried material should be poured with a bucket of water, infused for 4-5 days, drain.
In the fight against the strawberry parasite effectivelyspraying garden plot decoction of tomato tops. For its preparation, 1 kilogram of dried green mass is required to be poured with 10 liters of warm water and insisted for 3-4 hours. After this, the infusion should be boiled for 2-3 hours, drain, dilute with water in a ratio of 1: 2, add 40 grams of laundry soap. Apply for its intended purpose: process the beds with strawberries.
Посадки земляники рекомендуется полить отваром garlic at the rate of about half a pound per bush. To enhance the effect, the treated plants should preferably be covered with plastic wrap for several hours. Spraying pesticides (for example, the drug "Karbofos") is recommended only after harvesting the fruit. In the process of their conduct, young foliage should be abundantly moistened, since the strawberry mite, for the most part, lives on it.
Warming against strawberry mitesoil. To do this, after harvesting, it is necessary to mow all the leaves, in 3-5 days to treat the area with fire (using a gas torch), then pour the plants abundantly. Further care of the bushes is reduced to measures for weeding, feeding and shelter for the winter.
Preventive measures
In the fight against strawberry pest is very importanttake preventive measures: the landing should be kept clean, well lit and ventilated. You should not plant berry bushes in shaded areas, as well as in areas with stagnant water.
Recommended activities before landing
For planting strawberries required to useonly healthy seedlings. When using seedlings of own production, young plants are recommended to be fully immersed in hot water for a quarter of an hour, then rinsed in cool water and planted in the ground. This treatment should be carried out no later than mid-August: before the winter period, seedlings should build up a good root system, from 3 to 5 leaves and a well-developed growth bud. With early detection of strawberry mite, both damaged bushes and those located next to them should be removed. An effective measure to combat the parasite is to maintain crop rotation: strawberries can be returned to their original location no earlier than 4 years later.
