Valley Verti Micro Bio Pesticide

Listing ID #3602957

Verticillum is a fungi, which parasites on perts. Such fungi are also called opportunistic fungi. Biological control is a device to manipulate biosphere against pests for achieving maximum benefits. This can be done by changing the environment, by addition of organic amendments or by introducing other organisms. In general there are a few natural components which are present at level to be sufficient for suppression of perts development, while some other type of agents have been applied by man for the purpose.
There are numerous micro-organisms that prey or parasitize on perts :

• Trapping fungi
• Endoparasitic fungi
• Egg parasitic fungi
• Veticillum parasitises on eggs & cysts of nematodes.

Effects of Product :

• Many nematode-antagonistic fungi produce secondary metabolites and enzymes that demonstrate toxicity against plant-parasitic nematodes.
• The effects of fungal culture filtrates of Verticillium lecanii hybrid strains on mature eggs, embryonated eggs (eggs fertilized but without development of juveniles), and second-stage juveniles (J2) of Heterodera glycines and to compare these effects with those of their parental strains.
• The fungal culture filtrates of certain hybrid strains inhibited egg hatch of mature eggs. Furthermore, the fungal culture filtrates of two hybrid strains, AaF23 and AaF42, exhibited high toxicity against embryonated eggs of H. glycines.
•  However, most of the fungal culture filtrates of V. lecanii did not inactivate J2.
• The enzymes or other active compounds produced by the fungal culture filtrates of V. lecanii exhibit activity against specific stages in the H. glycines life cycle. In addition, based on a visual assessment of the morphological changes in eggs caused by filtrates of each strain, there were differences between the hybrid strains and their respective parental strains with regard to the active substances produced by V. lecanii against the embryonated eggs
