Experienced growers are aware of the benefits of preplant potato preparation, in which tubers are treated with diseases and pests. This article will discuss the safest and least time-consuming ways to protect. Potato seed can be protected from the Colorado potato beetle, a bear and a wireworm for a long time and at the same time save time and money. We have reviewed the drugs that will help solve the problem of combating diseases and pests without chemicals.
Protection of potatoes against 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 medvedka, choose Ritatoks Rubit in pellets from the manufacturer TPK ROST. This bait operates in two ways.
First, the granules added to the well during planting dissolve very slowly. The active ingredient - imidacloprid (class Neonikotinoidy) gradually enters the aboveground part of the plant, when eaten by the pests affects the central nervous system. The tool 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 “Rofatoks” is that the granules contain an aromatic additive, which is very attractive for wireworms and a bear. Eating the granules, the pest will not touch the potatoes. The drug is not phytotoxic, will not cause any harm to the plant itself. Means gets only to elevated part.
Method of administration Cuts “Rofatoks” in granules
All you need to do is to plant a remedy in the amount of half a teaspoon when planting in each well. The tool is applied once to forget about the problem of pests up to two months.
The cost of the drug Rubit “Rofatoks” 1 kg (enough to process 3 acres) is about 100 rubles.
At the stage of choosing the seed, discard the infected tubers and choose such places for planting potatoes, where there will not be a long stagnant moisture after rain or watering. And also observe the crop rotation of potatoes and agricultural techniques of fertilization. All of these measures reduce the risk of disease culture.
If you find signs of disease in the potato tops
The drug cuts “Diskor”
Use drugs on the sheet, for example chops “Diskor”. This is an effective result with low financial costs. The tool protects against Alternaria, scab, powdery mildew, leaf spot, black spot, black and gray rot, clusterosporiosis, leaf curl, cercosporosis, coccomycosis, oidium.
Cuts "Discor" is not phytotoxic, that is, does not cause burns of leaves and deformation of fruits. It can be used in phases: green cone, rose bud, flowering and fruit growth.
Active ingredient Hacks “Discor” - Difenokonazol. The tool penetrates the plant tissue, completely inhibits the growth of subcuticular mycelium, reduces the level of pathogen sporulation. It can be noted that the drug acts very gently and can increase the surface of the leaf.
Method of application of fungicide Cuts “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 weave, the consumption depends on the growth phase of the plant, 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. The treatment of tubers before planting will help from Alternaria, scab, powdery mildew, black spot, black rot, clusterosporiosis, gray rot, leaf curl, chickens, coccomycosis, and oidium. The tool will positively affect the germination of planting material.
The cost of the ampoule Cuts “Discor” 2 ml of about 30 rubles, one ampoule is enough to process up to 1, 5 weave.
Copper sulfate will protect against scab, Alternaria, rhizoctoniosis, and other fungal diseases.
Method of use for copper sulfate
For prophylaxis use 0.02% (2 g per 10 l of water) solution of copper sulfate. 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 preparation (20 g per 10 l of water). After two weeks it is recommended to repeat the treatment. 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 Bordeaux mixture.
Before putting into storage, pre-selected seed tubers are sprayed with a 0.5% solution of the preparation (50 g per 10 l of water).
Cost Cuts “Copper Vitriol” 300 gr about 100 rubles.
Preseeding protection of potatoes in areas infected with infection
In addition to the "Disco" to protect potatoes from disease can be used - "Fitolavin Agrouspekh." “Fitolavin” is a biological fungicide against root mucous and vascular bacteriosis, as well as leaf bacteriosis and blackleg.
Method of use “Fitolavin Agrousppeh”
Conduct the treatment solution for 2-3 days before planting 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 acts at a temperature not lower than +18 C.
The treatment of tubers with “Fitolavin” will help protect the crop from damage by fusarium, blackleg, rhizoctoniosis, anthracnose and other diseases. “Fitolavin Agroupeh” will accelerate the emergence of potato sprouts up to 3 days, increase the germination of tubers, increase the number of sprouts to 15%. In general, the drug contributes to an increase in yield of about 10% (subject to the observance of agricultural techniques).
Vegetable growers are recommended for 5-6 days before planting to process germinating seed potatoes with Fitolavin tank mixture (0, 2, 0, 5%) and microelements (0, 02-0, 03%), first of all boron, manganese and copper, with the subsequent preservation them in wet conditions at + 18 ... + 22 ° C.
The cost of “Fitolavin Agrousspeh” 20 ml is about 50 rubles.
Using any preparation, strictly follow the instructions on the package and take precautions.
