The filamentous fungus Paecilomyces is currently being developed as a biocontrol agent against plant parasitic nematodes, which often cause black leaf disease in pepper and coffee trees. Nematode eggs and cuticles are the infection sites for biocontrol agents that penetrate those areas by the production of lytic enzymes. Paecilomyces variotii NV01 was isolated from pepper soil from the Dak Lak province. The purpose of this work is to study the activity of protease and chitinase in the strain Paecilomyces variotii NV01. The protease activity was determined to be 82.3 U/ml in a 0.

Trichoderma harzianum parasitism on Meloidogyne incognita eggs and juveniles was examined in-vitro under Assam condition. M. incognita egg masses, their derived eggs and second-stage juveniles (J2) were parasitized by T. harzianum. The conidia of the T. harzianum were found inside of the eggs and attached to the J2s with the gelatinous matrix. The eggs were penetrated and parasitized by the hyphae of T. harzianum, while eggs containing juveniles were also parasitised by T. harzianum. Further, isolate T. harzainum was used for to know the bio-efficacy against M.

In the greenhouse conditions, we show that rootstocks are different in the degree of susceptibility to Broomrape. Attachment number, emergence number, and fresh matter of parasitic broomrapes are affected by rootstock genotype. A significant impact of the parasitism onto the dry weight of all infected tomato rootstocks with variable degree is observed.
