Methods to increase effectiveness of the nematophagous fungus <i>Duddingtonia flagrans </i>preparation
Nematophagous fungi for a long time are used for protection of agricultural crops against parasitic нематод. Efficiency of biological preparations can be increased due to perfection of ways of their application. We have shown that entering into soil of a biological biopreparation on the basis of the strain Duddingtonia flagrans F$882 in the period before the peak number of nematodes allows to lower the charge of a preparation in 4-8 times. The additive of nitrate of ammonium stimulates process of formation of traps for nematodes and also allows to lower the charge of a biological preparation.
