PACER ® is a biological insecticide based on a selected strain of naturally-occurring entomopathogenic soil fungus Metarhizium anisopliae (NCIM 1311 ) that infects and kills root grubs , termites , ants , locusts and many soil insects.
PACER ® contains spores and mycelial fragments of Metarhizium anisopliae . It is formulated as Powder with CFU count of 1 X 10 ^ 8 / g. PACER ® is registered by Indian Pesticides Regulatory Authority - Central Insecticides Board, Govt of India. PACER ® is approved for use in Organic agriculture. The strain of Metarhizium anisopliae is owned by Agri Life.
Mode of Action
Conidial penetration : The conidial spores get attached to the host by entering through the hosts spiracles and pores of its sense organs and start germinating. Surface growth on cuticle occurs to a limited extent where the fungus derives nutrition from the lipids in the cuticle. 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 skeleton (cuticle) of the host. The fungus produces a lateral extension of hyphae inside insect body which proliferate and start feeding on insects internal contents
Enzyme production : Fungal extracellular enzymes mainly the proteases help penetration of insect cuticle through localized hydrolysis. PACER ® mycelia produce secondary metabolites that helps the fungus overcome the host defences.
Growth : Hyphae continue to grow till mycelia fills the entire insects body. After consuming internal contents ( haemolymph ) the fungus breaks out of insects cuticle and starts sporulating making the insect appear fuzzy. After its death the host is seen to be enveloped by a mat of conidia. PACER ® infects the insect on contact and does not need to be consumed by the host to cause infection. Metarhizium anisopliae establishes Infection between 24 to 48 hours. The infected insect may live for three to five days after hyphal penetration and after death of host insect pest, the conidiophores bearing conidia are produced on cadaver..
Horizontal Transfer effect : PACER ® has unique Horizontal Transfer Effect (HTE) unlike any chemical termiticide. Normal chemical termiticides when drenched on soil, enter mostly vertically down in soil and partially horizontally. Only the termites coming in direct contact with the chemical termiticide get killed without affecting the large travelling colony and queen who remain safe in their soil haven. Whereas, PACER ® being a Bio Termiticide having Horizontal Transfer Effect starts multiplying horizontally also due to availability of moisture and target pests. Termites being social insects, have a definite pattern of movement in colonies and finally all workers reach the termitarium where the Queen resides. PACER ® being a microbial product starts pathogenising the workers and as the workers move in colonies and touch each other, the spores get transferred from one worker to another and thus the spores finally reach the Queen also. The queen produces as many workers by parthenogenesis and hence only killing the workers is not effective. It is important that the spores reach and infect the queen in the termatorium. Thus the entire colony of termites get pathogenised and PACER ® offers long term control.
Method of Application
Soil Application : Mix PACER ® @ 5g/ L of water and decant the supernatant liquid and apply through drip irrigation, flood irrigation, spraying on soil , drenching the root zone. PACER ® can also be mixed with organic fertilizers , vermicompost / neem cake and applied to root zone.
Termatarium application :Destroy the termatarium and drench the termatarium area with liberal quantity of water with PACER ®. Suggested dilution is 5 g/Lt of water.
Drenching soil spray : Mix PACER ® @ 2.5 Kg in 1000 L of water and spray to control termites in various crops like groundnut, wheat , sorghum and other millets.
Mix PACER ® @ 5 g / L of water and spray for control of Lepidopetrous pests / Caterpillar pests and locusts The spray volume depends upon the crop canopy.
Termites , Root Grubs ,Locusts , Root weevils , Ants , Beetles and caterpillar pests
PACER ® is suitable for application on Groundnut, Wheat , Sorghum, Cereals , Millets , Pulses, Oilseeds, Fibre Crops , Sugar Crops , Forage Crops , Plantation crops ,Vegetables, Fruits, Spices , Flowers , Medicinal crops , Aromatic Crops , Orchards and Ornamentals
PACER ® is stable for a period of 12 months from the date of manufacturing.
