Abstract

This invention relates to chemical agents that affect the growth and development of potato plants, and can be used in agriculture. The purpose of the invention is to increase the yield. According to the invention, potato plants are treated with a 0.001-0.01% solution of triisononyloxypropylammonium methyl phosphonate in the flowering phase. The potato crop rises by 11–13%, while the well-known analogue in structure increases the crop by 5%. Substances treated with the substance can be planted a week later, thus avoiding frost damage to seedlings. This increases the mass of the roots and seedlings. 5 tab.

Description

This invention relates to chemical agents that affect the growth and development of potato plants, and can be used in agriculture.

The purpose of the invention is to increase the yield.

The use of triisononyloxypropyl ammonium methylphosphonate (BF-51) at a concentration of 1-2000 ppm regulates plant growth: the formation of the root system, the growth of the stem, the maturation of the crop. The dose used depends on the type of plant, the purpose of the treatment, the phenological stages of the plant, and the like.

with

90 g of talc, and methanol is evaporated under reduced pressure. A dusting agent is obtained containing 10% of the biologically active substance, the adhesive ability of which is 0.05 / 0.01 g / cm.

EXAMPLE 5 A mixture of 10 g of BF-51, 10 g of polyethylene glycol, 0.1 g of emulsion additive N090 (alkylaryl polyglycol ether) and 100 ml of methanol are evenly mixed with 79.9 g of talc, and methanol is evaporated. with low pressure. A moisturizing powder containing 10% of a biologically active substance is obtained, the adhesive ability of which is 0.07-0.01 g / cm4.

EXAMPLE 6 A mixture of 10 grams of BF-51, 5 grams of polyvinylpyrrolidone, 0.2 grams of the arch of N080 (nonylphenol ether-polyglycol) and 100 grams of methanol are uniformly mixed with 84.8 grams of talc, and methanol evaporated under reduced pressure. A moisturizing powder containing 10% of a biologically active substance is obtained, the adhesive ability of which is 0.01-0.002 g / cm.

Example. 100 g of fine kieselguhr is vigorously mixed with 100 g of BF-51, after settling for 2-3 hours, the solution is filtered and dried for 1-2 hours at 40 C.

Try on 100 g of fine kieselguhr, 100 g of BF-51 and 25 g of sapemate (synthetic silicate) are vigorously mixed, then do as described in Example 7.

EXAMPLE 9. Potato sprouts removed from potato tubers were soaked for 10 minutes in solutions that contain test substances in various concentrations, then they are planted in growing pots.

3-Indolylacetic acid (IAA) and gibberylic acid (GA) were used as reference substances. Weights of roots, shoots and tuberous processes were weighed “The results are shown in Table 1.

drying the surface of the seeds is planted in growing pots and after 2 months. estimate the percentage of seedlings and the average length of the shoots. The results are shown in Table 2c.

Example 11. Beet seeds (Kamenna variety) are soaked for 10 minutes in solutions containing test substances in various concentrations. After drying the surface, seeds are planted in growing pots and after 2 months. estimate the percentage of germination. The results are shown in Table 3.

Example 12. Planting tubers are pickled with BF-51 containing solutions of different concentrations of the concentrate dissolved in water, described in Example 3, and planted after 8 days. Untreated control tubers are planted simultaneously or one month earlier (early planting). Was estimated harvest. The results are shown in Table 4.

Based on the results, it can be stated that the tubers treated with BF-51 can be planted a week later, while the planted plants will not lag behind in their development. This is especially important for areas where early planted potatoes may be damaged by unhealthy cold spring weather.

Example 13 (comparative) ,, Experiments in a heated film greenhouse on 1 surface, with four repetitions with Desiree type potatoes.

Processing was carried out at the stage of bloom with a spray solution of 0.01-0.001%. Experiments were evaluated by measuring the yield.

The results are shown in Table 5.
