Larvae of the black soldier fly Hermetia illucens effectively use fruit and vegetable mixtures as a feed substrate-waste of retail chains, including those infected with nematodes. It is shown that the larvae are capable of high speed to dispose of the potatoes (for the 12 day it reached 70% conversion of substrate) and completely eliminated in the affected root as the potato plant pathogenic nematode Ditylenchus destructor and saprobiotic nematode Rhabditis spp., which impair the commercial properties of potatoes and other root crops during storage. In the control substrate without larvae of the black soldier fly phytopathogenic nematodes were preserved during the study period, and saprobiotic nematodes multiplied. Introduction derived from fruit and vegetable waste zoocompost (excrements of the larvae with the remains of undigested substrate) to the soil reduces the infectivity of tomato root-knot nematode Meloidogyne incognita. The introduction of compost under the root system immediately before the infection of the 2-month tomato seedlings reduced the negative impact of the nematode, the plants were more powerful than the infected control. Plants treated with zoocompost at a dose of 6.5 g / plant were particularly distinguished: the mass of their above-ground part and the height of the stem was close to uninfected control. Shown the prospects of using to compete to stimulate growth and development of plants, especially of plants suffering from nematode infestation.
