It seems that the potato is a simple, unpretentious plant, grows by itself, the sun drives it, it rains, the participation of a person is almost not required. If this is true, it is only partly. The potato is responsive to all agricultural techniques, it needs a rational watering. And the significance of protection against the Colorado potato beetle is out of the question. That's about how to grow potatoes and talk, because a good harvest is largely man-made.
To care for potatoes, especially if it is planted not on the field, but on the garden plot, especially exemplary potato growers and potato lovers begin when it has not yet risen. Before seedlings, one or two times loosening is carried out to destroy the weeds that appear before the potato. At the same time, they destroy the soil crust. It is clear that this is an ideal care option.
But even with the appearance of seedlings, it is necessary to loosen and spud. The first time it is necessary to do this when the plants reach a height of 12-15 cm. After cultivation, it would be good to water the potato plot. The second hilling can be carried out 20 days after the first.
Watering plays an important role in obtaining high potato yields. Watering should be rarely, plentifully, to wet the soil layer to a depth of 40-50 cm. Water 3-5 times with an interval of 7-10 days. If watering is difficult due to a rare or unsystematic water supply in gardening, then you need to adapt and carry out three waterings: after emergence, during budding and after flowering.
Top dressing should be timed to the same three periods. At 10 m2 3-5 kg of rotted manure or 2 kg of bird droppings should be introduced. If there are no organic fertilizers, 100-150 g of ammonium sulfate or 80-100 g of ammonium nitrate and 150-200 g of superphosphate can be added. On irrigated areas, plants are fed after rain. At the infield, mineral fertilizers must be applied directly to the row or hole, otherwise weeds in the rows will receive nutrition.
Early potatoes are harvested when the tubers reach a size of at least 3 cm in diameter (with a chicken egg). This usually happens when flowering ends and yellowing of the leaves of the leaves begins. Potato bushes are carefully dug up with garden forks on the side of the ridge so as not to damage the crop, they pull the bush by the tops and remove the tubers.
Colorado potato beetle protection
Everyone who has acquired a potato "plantation" should remember that summer care consists not only in timely hilling and weeding, but also in protection against pests. The very first of them is the Colorado potato beetle. The main thing is not to miss the moment of the beginning of laying eggs of the Colorado potato beetle. As soon as the first pests are found on the site, they must be collected within five days without fail. And then collect as often as possible.
If it is not possible to constantly visit the site and collect beetles in a timely manner so that they do not have time to devour the plants, then it makes sense to resort to chemical treatment and stop worrying about the future harvest.
The optimal time for treatment against the beetle is mid-June, well, a maximum of the third decade of the month. Then do not have to handle in July. This will have a beneficial effect on product safety, because by the time of harvesting (60 - 80 days after processing), most likely there will be no residues of chemicals in the potato. In the usual treatment regimen, only 40 to 45 days remain before harvesting.
In all cases, treatment against the Colorado potato beetle must be combined with foliar application.
In cool years, in the fight against beetle, you can limit yourself to bioprotection - Bitoxibacillin, Fitosporin and others.
Using any medications, carefully read the instructions on the packaging and follow the manufacturer's advice.
