PAECILO ® is a biological nematicide based on a selected strain of naturally-occurring fungus Paecilomyces lilacinus that infects and kills eggs , larvae and adult stage of many plant pathogenic nematodes like root knot nematodes , cyst nematodes remiform nematode , burrowing nematode , citrus nematode , golden cyst nematode and lesion nematodes. Paecilomyces lilacinus is parasitic to eggs and egg masses of nematodes.
PAECILO ® contains spores and mycelial fragments of Paecilomyces lilacinus . It is formulated as Powder with CFU count of 1 X 10 ^ 8 / g. PAECILO ® is approved for use in Organic agriculture.
Mode of Action
Conidial penetration :Paecilomyces lilacinus on getting attached to the host forms a dense mycelium that gives rise to conidiophores. These bear phialides at the ends of which spores are formed in long chains. The fungus produces an appressorium (a swelling on the end of the germ tube) which marks the start of invasion of insect. The appressorium produces a penetration peg that enters the external skein (cuticle) of the host. The fungus produces hyphae inside insect body which proliferate and start feeding on insect’s internal contents.
Enzyme production : Paecilomyces lilacinus produces proteases and chitinase enzymes that weakens nematodes so as to enable a narrow infection peg to be established and push through the insect’s exterior and pathogenise it from within. A novel nematicidal compound is present in PAECILO ® that weaken the nematodes and then gets inside the insect and kills the infected nematode.
Growth : Once inside, PAECILO ® replicates and consumes the nematodes' internal organs and blood-like fluid, the hemolymph eventually killing it. PAECILO ® infects the nematode on contact and do not need to be consumed by nematode to cause infection.
Environment factors : The rate at which PAECILO ® kills the nematode is dependent on temperature and humidity. High humidity is essential for conidial germination and infection establishes between 24 to 48 hours. The infected nematodes may live for three to five days after hyphal penetration and, after death of nematode, the conidiophores bearing conidia are produced on cadaver. The fungus is specific to Nematodes. Nematodes die before the fungus is visible. Paecilomyces lilacinus grows best at 20-30 degree C and at a relative humidity above 65%.
Method of Application
Seed Treatment : Mix 10 g/ Kg seed by making a slurry and coat the seeds with this slurry. Dry the seeds under shade and sow them.
Nursery application : Mix 50 g / sq mt of PAECILO ® in nursery bed and apply 2 Tonnes / Acre of FYM before transplanting
Polyhouse application : Mix 50 g / sq mt of PAECILO ® in green house at an interval of 3 months for crops such as capsicum , brinjal . tomato and okra ( lady’s finger )
Soil application : Apply FYM/ compost enriched with PAECILO ® @ 2 Kg per plant at the time of planting and at an interval of 3 months after planting for crops such as acid lime and papaya.
Actual application dose per Acre or Hectare depends on density of nematode population. 50 – 500 Kg/ Ha of PAECILO ® may be needed.
FYM enrichment : Mix 5 Kg of PAECILO ® with 1Tonne of FYM /compost. This should be left under shade for 15 days with adequate moisture. Mix thoroughly at an interval of 5 days to enrich the FYM /compost with PAECILO ®.
