How to protect strawberry plants from diseases after harvest

The harvest of the berries has been gathered and now we must immediately proceed to the sanitary inspection of the strawberry plantation for diseases and damage by pests.


White leaf spotAs a rule, always appears during the harvest of berries. This is facilitated by wet weather, high humidity and dense planting.Leaves form small grayish or brown spots with a red rim. With a strong defeat, they merge, and the leaves dry out. In this case, it is necessary to remove the fallen leaves, cut off the affected leaves and make a comprehensive feeding.


Phytophthora rot(Fusarium wilt) harms not only strawberries, but also the soil. Plants "burn", fade. A variety of these fungi more insidious. Ill not only the aboveground part of the plant, but also the root system. The rhizome of the inside is affected by red-brown rot.Unripe green berries turn into a brown state, and become inedible dense or leathery, and rot.


Finding such a disease, it is necessary to take radical measures. Carefully dig the diseased plant with a clod of earth and take it out of the garden area, the garden tools are washed. At the same time, the soil hole is disinfected with a copper-containing preparation, or with a chemical agent against late blight (Ridomil Gold, for example). It is possible to shed phytosporin several times, apply fungicides such as Maxim, Vitaros, or sow calendula, marigolds, which heal the earth, and crush them in late autumn, and leave them to rot at this point.


In order to prevent the spread of this disease, it is necessary to destroy diseased bushes, observe crop rotation, do not feed strawberries with nitrogen, thin out in time and destroy weeds in strawberry beds. It is better not to dig up the soil, but to mulch. Mustache from affected plants can not be taken.


Gray rotcauses significant damage to crops, especially with high humidity and thick planting. Spores of fungal rot by wind and rain spread throughout the plantation and overwinter well. Therefore, the fight with the "fluff" spend every season.As a rule, rotten berries are harvested simultaneously with the harvest in a separate container and buried; it is unacceptable to throw them into the compost.After harvesting, it is better to cut the leaves and process the bushes of strawberries and the ground around the Bordeaux mixture. Effective making and dusting plants with wood ash.


Spider mitein the hot dry summer adds disappointment. Especially tick resistant varieties. The leaves develop poorly, the bush becomes "chewed" and such plants must be treated with insecticide.Good help against sulfur ticks. Processing one of the drugs, for example, karbofos (Fufanon) against strawberry weevil, leaf beetle will also be appropriate.
