THE EFFECT OF PHOSPHOROUS ACID ON THE FUNGICIDAL ACTIVITY OF CARBENDAZIM AND TEBUCONAZOLE

Fungicidal compositions have been developed for dressing of seeds and protecting crops of cultivated plants from phytopathogenic fungi. Fungicidal compositions as active ingredients contain methyl ester of 2 benzimidazolylcarbamic acid (BMC, carbendazim) and phosphorous acid in a mass ratio of 3 : (1-1.5), respectively, and tebuconazole with phosphorous acid in a mass ratio of 1 : (1-5). The formulation is in the form of a flowable suspension paste. The fungicidal activity of the fungicides on wheat seedlings was studied and field tests were carried out. The proposed fungicidal compositions have a synergistic effect, which reduces the consumption rates of active substances, reduces the fungicidal load on the environment, stimulates plant growth, and increases the yield of grain crops.
