control was 83 weeds. Increased to a periodmore weeds pop up on sqm. In variant V3 werefound 32 plants in the experimental group,while the number of weed control increased to105 plants.Note that 20 days of treatment increased thenumber of weeds experience with 32 plants andthe weed control number increased by 41plants, the total number of weeds in group sqmwere 3.28 times higher than experience. Gasconsumption flame burning weeds in tomatocrop, calculated at an area of 1000 squaremeters, according to Table. 4:Table 4.

Suchweeds were counted on a square before treatment,and at 30 days after treatment plants werecounted according to the type found in them.The results are shown below:Table 5.

Combustionwas achieved at temperature of 70-80 o C, so protein coagulates and weeds die.Results of weed biodynamic methods, the ratioof 1:9 ash to dry soil are presented in thefollowing table.The results show that the percentage of allexisting weed control cultures is reduced by22% for creeping couch grass, bindweed and28% to 16% for veronica. Reproduction isinhibited by the introduction of new weeds intothe soil ash obtained by burning their seeds.This is repeated for 3-4 consecutive.Table 6.
