Yakov Bogatin: Cucumbers diseases

Yakov Bogatin says that in sharp cooling at night multifaceted light rough spots might appear on the leaves of cucumbers, mostly closer to the edge of the sheet. Such spots are growing quickly. Finally, on the underside of the lead raid gray-olive color appears and consequently the lead dies. This is called a Downy mildew. This is the moment when farmers should stop watering and fertilizing, the moment when it is necessary to dry a little greenhouse ventilation.



Olive leaf spot is a fungal infection when yellow-brown spots appear on the leaves and the fruits are formed dark watery spots; fruits become distorted. The disease usually appears in late summer. Toeplitz aired and the affected parts of the plants destroyed. In the second half of summer, usually in late July there is a gray mold - the stems and petioles becoming slippery. To combat the disease in the greenhouse there should always be a glass filled with pink creamy mass - a mixture of chalk, water and potassium permanganate. Yakov Bogatin says that it is necessary to decay wipe a tuft of glass or cut rough leaves of cucumber, cut a smear "cream". If you do this in the morning and evening the sore spot will dry.



While weather is warm usually all of these diseases are limited. But here comes the cold wave. After a few cold days some leaves on a number of plants begin to wilt. In the evening when the sun goes down everything is restored. In the future it is repeated but with each passing day the plants wither stronger and stronger. There comes a day when the evening they had not come to their senses and gradually all the leaves wither. Yakov Bogatin claims that this is too late and the plant can not be saved.
