Experienced vegetable growers know about the advantages of pre-planting potatoes, in which the tubers are treated with remedies for diseases and pests. This article will focus on the safest and least labor-intensive methods of protection. Potato seed can be protected from the Colorado potato beetle, bear and wireworm for a long time, and at the same time save time and money. We made a review of drugs that will help solve the problem of combating diseases and pests without unnecessary load of chemicals.
Protecting potatoes from pests on healthy soils
If the land is not infected with pathogens of fungal and bacterial diseases, and the main enemy of the potato is the Colorado potato beetle, wireworm and bear, choose Rofatox Rubit in granules from TPK ROSTI manufacturer. This bait works in two directions.
First, the pellets added to the well during planting dissolve very slowly. The active ingredient - imidacloprid (class Neonicotinoids) gradually enters the aerial part of the plant, when eaten by pests, the central nervous system is affected. The product will protect all crops for which pests are dangerous - be it potatoes, eggplant, cabbage or others.
The second direction of protection of the drug Rubit "Rofatox" is that the granules contain an aromatic additive, which is very attractive for the wireworm and the bear. By eating the pellets, the pest will not touch the potatoes. The drug is not phytotoxic, will not cause any harm to the plant itself. The agent enters only the aboveground part.
Method of application Cuts "Rofatox" in granules
All you need to do is, when planting, add half a teaspoon of the product to each hole. The tool is applied once in order to forget about the problem of pests for up to two months.
The cost of the drug Rubit "Rofatox" 1 kg (enough for processing 3 acres) is about 100 rubles.
At the stage of seed selection, discard infected tubers and choose places for planting potatoes, where there will be no prolonged stagnation of moisture after rains or watering. And also observe potato crop rotation and fertilization techniques. All these measures reduce the risks of disease damage to the culture.
If you find signs of disease on the tops of potatoes
The drug Rubit "Discor"
Use drugs on a sheet, for example Rubit "Discor". This is an effective result at low financial costs. The product protects against alternaria, scab, powdery mildew, leaf spot, black spot, black and gray rot, clusterosporium, leaf curl, cercosporosis, coccomycosis, powdery mildew.
"Discor" cuts is not phytotoxic, that is, it does not cause leaf burns and fruit deformation. It can be used in phases: green cone, pink bud, flowering and fruit growth.
The active ingredient Rubit "Discor" is Difenoconazole. The agent penetrates into plant tissues, completely inhibits the growth of subcuticular mycelium, and reduces the level of sporulation of the pathogen. It can be noted that the drug is very mild and can increase the leaf surface.
Method of application of fungicide Rubit "Discor"
During the growing season, at the first signs of the disease, spray the plants 2 times with an interval of 10-14 days. 2 ml of the drug must be diluted in 7 liters of water. The working solution (7 liters) is enough for processing from 1 to 1.5 acres, the consumption depends on the phase of plant growth, weather conditions and other factors.
For dressing tubers before planting: dilute 5 ml of the drug in 2 liters of water and process the seed. Treatment of tubers before planting will help against Alternaria, scab, powdery mildew, black spot, black rot, clusterosporium, gray rot, curly leaves, cercosporosis, coccomycosis, oidium. The tool will positively affect the germination of planting material.
The cost of an ampoule Rubit "Discor" 2 ml is about 30 rubles, one ampoule is enough for processing up to 1.5 hundred parts.
Copper sulfate will protect against scab, alternaria, rhizoctonia, and other fungal diseases.
Method of using copper sulfate
For prophylaxis, a 0.02% (2 g per 10 l of water) solution of copper sulfate is used. The first time potato bushes are sprayed when their height reaches 15-20 cm.
When the first signs of late blight appear, the potato plantation is sprayed with a 0.2% solution of the drug (20 g per 10 l of water). It is recommended to repeat the treatment after two weeks. Potatoes are allowed to be eaten, not earlier than 2 weeks after the last spraying.
Some varieties are particularly sensitive. In order not to burn the tops, it is better to use not pure copper sulfate, but a Bordeaux mixture.
Before storage, pre-selected seed tubers are sprayed with a 0.5% solution of the drug (50 g per 10 l of water).
Cost Chops "Copper sulfate" 300 gr about 100 rubles.
Pre-sowing protection of potatoes in areas infected with infection
In addition to "Discor", you can use "Fitolavin Agrouspech" to protect potatoes from diseases. "Fitolavin" is a biological fungicide against root mucous and vascular bacteriosis, as well as leaf bacteriosis and black leg.
Method of application "Fitolavin Agrouspech"
Treat with the solution 2-3 days before planting the potatoes. This technique has a beneficial effect on plants, improves their immunity, activates growth processes and helps to increase the productivity of the planted variety.
Important! The drug works at a temperature not lower than +18 C.
Treating tubers with "Fitolavin" will help protect the crop from damage by Fusarium, blackleg, Rhizoctonia, anthracnose and other diseases. "Fitolavin Agroupech" will accelerate the emergence of potatoes up to 3 days, increase the germination capacity of tubers, and increase the number of sprouts up to 15%. In general, the drug helps to increase yields by about 10% (subject to agricultural practices).
It is recommended for vegetable growers 5-6 days before planting to process sprouting seed potatoes with a tank mixture of Fitolavin (0.2-0.5%) and microelements (0.02-0.03%), primarily boron, manganese and copper, with subsequent preservation them in humid conditions at + 18 … + 22 ° С.
The cost of "Fitolavin Agrouspech" 20 ml is about 50 rubles.
When using any drug, strictly follow the instructions on the package and take precautions.
