Good day. Tell me what you need to do to save the large strawberry crop. I have varietal wild strawberries. Age 2-3 years. The first berries are large and quite a lot on peduncles. I learned to save from weevil. But after the first berries, the flower stalks along with the berries began to turn brown and withered. I think that I lost 50% of the crop. What kind of illness I do not know. Tell me what to do to cure the landing. Thanks in advance. Unfortunately, I did not take a photo.
Irina dare to suggest that two weeks before the berries dried, you had heavy rain, with a decrease in temperature to 3-6 degrees. July rains often provoke the appearance of gray rot. An increase in humidity in combination with a lower temperature provokes gray rot in the same way on strawberries grown in greenhouses. And since the disease struck at an early stage of flowering, the berries did not rot, but withered. The development of gray rot is affected by the variety and growing conditions. Especially it is necessary to pay attention to the thickening of plantings and abundant feeding with nitrogen, which weaken the immunity of plants.
Berries affected by the disease must be collected and destroyed. It is advisable to cut the leaves and spray the beds with a 1% Bordeaux mixture. Dig the aisles, introducing complex mineral fertilizers.
In the spring, even before the young leaves begin to grow, the beds need to be cleaned of old leaves, the straw litter should be removed and the bushes should be sprayed with 2-3% Bordeaux liquid.
Before flowering, spray the bushes with a solution of potassium permanganate or 1% Bordeaux liquid. When ovaries appear, you can cultivate the soil to prevent the development of gray rot with an infusion of ash (2 cups of ash per bucket of water), or pollinate ash at the base of the bushes.
