Rosselkhoztsentr warned about the massive spread of potato late blight.
Dry hot weather in July of this year held back the development and spread of late blight on potatoes, the branch of the Rosselkhozcenter in the Komi Republic reported.
When conducting phytosanitary monitoring by specialists, the first signs of late blight were found on the production plantings of potatoes with. Chukhlem, Sysolsky district, only on July 28. However, due to dry weather, the disease did not become widespread. Given that since the end of the first decade of August it has been raining in Komi and soil moisture has increased, the likelihood of mass spread of late blight has increased significantly.
If timely measures are not taken to protect potatoes from late blight, then the loss of tuber yield can reach 30% or more.
In this regard, we recommend that potato growers urgently conduct surveys of potato plantings and treat them with fungicides: Kuprolux, SP or Ordan, SP at the rate of 25 g per 5 liters of water with a working fluid consumption rate of 5l / 100m2 or other recommended preparations. When using chemical fungicides, strictly follow all the precautions indicated on the packaging.
