(54) METHOD FOR 1THE WASHING BY CARD A

The invention relates to agriculture, and specifically to phytosanitary techniques, which allow the release of seed crops of root and tuber crops, for example potatoes, from diseased bushes, ttptntsceA other varieties and undesirable plants of the specified culture. It is also applicable in all breeding centers for negative selection of perspectives of potato varieties and hybrids. The known method of potato phyto-cleaning, based on the use of carbation (Vapam), trapex, Simaznna, daOK, etc. ij. There is also known a method of phyto cleaning of potatoes, which includes the introduction of a herbicide into the soil under a bush, while chemical agents are used as a herbicide, in particular 2,4,5T, tormon-80, reglon, atrazine, and others. These chemicals are used in separate, and in certain ratios with other G2T components. However, known methods have toxic effects on the environment. In this case, inhibition of the growth of nearby potato bushes takes place, which leads to their deformity and decrease in productivity in the offspring. Treated unwanted potato plants often grow. In addition, the pesticides used also do not ensure the complete destruction of the tubers of the new crop of culled juyuns, which leads to the spread of pathogens through seed material. The purpose of the invention is to protect the environment from toxic effects while simultaneously stimulating the growth of nearby potato bushes. This goal is achieved by using a saturated solution of urea as a herbicide according to the method of phyto cleaning of potatoes, and the application is carried out to the depth of the uterine tuber. At the same time, a saturated urea solution is introduced in the period of full germination at a dose of 15-20 ml and in the flowering phase of 25-30 MP. Urea saturated solution in comparison with previously known herbicides does not poison and therefore ensures complete safety for people and warm-blooded animals, as well as prevents the environment and the atmosphere from pollution. Urea is widely available. Putting it into the soil at the base of the bush to the depth of the parent tuber leads to complete destruction of the plants, together with the progeny of unwanted potato clones. Re-growth of dead bushes does not occur. At the same time, urea has a stimulating effect on neighboring plants, which ensures their productivity. The urea solution (carbamide) is prepared in containers within which the agitator is accommodated. The ratio of water and urea is 1: 1. At the same time, granulated chevina is poured into water in small portions and constantly stirred until the granule is completely dissolved. Urea filling is stopped at the moment when the granules in the solution remain unchanged. This condition of the solution confirms its full saturation. This solution is introduced into the soil to the depth of the parent potato tubers, which causes the death of the root of the root system, and then in the whole above-ground mass of unwanted potato plants.

25 Table. Table 1 presents data on the effectiveness of the use of high-purity urea for chemical cleaning of potato crops. When the first crop of seed potatoes is cleaned, for example, the Sulev variety (plant height 15-16 cm), 15-20 ml of HacbmteHHoro urea solution is applied to one unwanted plant. Treated plants die on the seventh day. In the second chemical cleaning of potatoes (in the bloom phase), the preparation is introduced in a dose of 25-30 ml per plant. Complete extinction of unwanted plants is observed in ten days. Thus, 80-100 l of the total urea solution is consumed per 1 ha of sowing potatoes. In tab. 2 presents data on: the effect of a saturated solution of urea on tubers of treated bushes during the flowering period of potato plants. The resulting tubers of the new crop are mummified, blackened, and then killed by the meanness after making the whole solution. In tab. Table 3 presents data on the effect of a saturated urea solution on the productivity of potatoes adjacent to the treated plants (variety Sulev). A saturated solution of urea does not have a negative effect on neighboring bushes even with the smallest feeding area of 70 x 5 cm, but, on the contrary, causes a stimulating effect on yields to a number of growing plants.
