Abstract

DC60 (27/05/42) Agrochemicals with respect to the use of (a) phosphorus compounds containing at least partially organic lipophilic radicals with (b) urea and / or Urea derivatives In the selected quantity ratio of (a) to (b) as a soil additive for the control of plant parasitic soil nematodes. By biological means By increasing the potential of soils that are antagonistic to specific nematodes by Increase the growth of Antagonistic rhizosphere bacteria and / or Kills nematodes and / or existing mycorrhiza species Same result And at the same time increase the growth The plant grows in the soil This compound which increases the growth of bacteria. Ideally, being put in To occupy the roots in Form of an aqueous preparation using pre-plant compatible emulsifier and / or in During plant growth, elements (a) and (b) were used at the rate As for the quantity that the rate The weight of C to N is not greater than 61 and the ideal is not greater than 5: 1 Agrochemicals with respect to the use of (a) phosphorus compounds with at least some lipophilic organic radicals. In association with (b) urea and / or Urea derivatives The selected quantity ratio of (a) to (b) was a soil additive for controlling plant parasitic soil nematodes. By biological means By increasing the potential of soils that are antagonistic to specific nematodes by Increase the growth of Antagonistic rhizosphere bacteria and / or Kills nematodes and / or existing mycorrhiza species Same result And at the same time increase the growth The plant grows in the soil This compound increases the growth of bacteria. Ideally, being put in To occupy the roots in Form of an aqueous preparation using pre-plant compatible emulsion and / or in During plant growth, elements (a) and (b) were used at the rate As for the quantity that the rate The weight of C per N is not greater than 6: 1 and ideal is not greater than 5: 1:
