Bio Insecticides

Paecilomyces lilacinus is a naturally occurring fungus found in many kinds of soils throughout the world. As a pesticide active ingredient, Paecilomyces lilacinus is applied to soil to control nematodes that attack plant roots. In laboratory studies, it grows optimally at 21-32 degrees C,and does not grow or survive above 36 degrees C. It acts against plant root nematodes by infecting eggs, juveniles, and adult females.

Crops :

Eggplant, Potato, Chilli, Tomatoes, Cucumbers, Flowers, Orchards, Vineyards, Ornamentals in greenhouses, lawns, nurseries and landscape.

Target pests :

Plant parasitic nematodes in soil, examples include Meloidogyne spp. (root knot nematodes); Radopholus similis (burrowing nematode); Heterodera spp. and Globodera spp. (cyst nematodes); Pratylenchus spp. (root lesion nematodes); Rotylenchulus reniformis (reniform nematode); Nacobbus spp. (false root knot nematodes).

Beauveria Bassiana is an endomopathogeneic fungi and it widely used as bio-insecticide for the pest control of agricultural, ornamental and forest plants. Bio-pesticides made on the base of B. bassiana are effective against various species of thrips, beeteles and aphids, the glasshouse whitefly, larvae of colorado beetle and also several species of leaf-gnawing pests.


Mode of action:

The action of B.bassiana on insects begins from the penetration of spores in a body cavity through dermal coat (cuticle). Having penetrated in a body the spores germinate in hyphae, then a mycelium overgrows from which conidia split off. Having proved in the body the conidia begin to circulate in hemolymph. On this stage it is already possible the affection of insects by some strains in consequence of the excretion of the considerable quantity of toxins. If toxin is absent the mycelium gradually fills up the whole body of the insect. In the beginning muscular tissue is affected. Fungus growth continues until all the tissues are destroyed. The fungus can form conidiophores, which rupture the cuticle and the envelope of a dead larva. The affected insect is covered with white, wadded coating (conidiophores). Then it is observed spore maturation, and mass sporulation begins.


Advantages :

• Pesticidal activity takes place on different stages of insect ontogenesis;
• The fungus possesses fast growth, and high specificity.
• It is able to remain for a long time in nature without the decline of entomopathogenic activity;
• The first signs of pesticidal action are observed in 5–7 days after treatment.
• The effectiveness of this product depends very much on climatic condition (Temp 25–28°c and relative air humidity of 80–90%), the methods of application and doses.

Metarhizium Anisopliae is an entomopathogenic fungus that infects insects that come in contact with it. Once the fungus spores attach to the surface of the insect, germinate and begins to grow, they then penetrate the exoskeleton of the insect and grow very rapidly inside the insect, causing the insect to die. Other insects that come in contact with infected insects also become infected with the fungus.


Mode of action

The spores of this fungus when come in contact with the cuticle (skin) of susceptible insects, they germinate and grow directly through the cuticle to the inner body of their host. The fungus proliferates throughout the insect’s body and draining the insect of nutrients, eventually killing it.


Recommended Crops

Cereals, Pulses, Vegetables, Fruit crops, Cole crops, Orchards, Fibre crops, Cut flowers, Ornamentals in greenhouses, nurseries, lawns and landscape.


Target pests

Root weevils, plant hoppers japanese beetle, black vine weevil, spittlebug and white grubs.

Verticilium lecanii is an entomopathogenic fungus and it is widely used as a component of biological systems in agricultural crop defense. This bio-pesticide fungus which affects various species of phytophages especially on aphids, mealy bugs, thrips, mites and nematodes.


Mode of action :

The entomopathogenic fungus infects phytophages by means of penetration into insect epidermis. The spores of v. Lecanii germinate on insects and fungus strings (hyphae). Usually they grow on the sweet excretions of whiteflies (the products of life activity) or on carbohydrates, which are added in biopesticides. As a result of it insects commit as if autoinfection. The fungus is also able to direct its hypha growth directly to the insects escaping this external phase. Further the inside development of the fungus kills the insect. Although it is rather difficult to determine the exact cause of death the main factors resulting in lethal outcome are: the mechanical destroying of respiratory ways and hemolymph circulation, the exhaustion of nutrient reserves and the breaking of organ functions, the synthesis of specific proteins by the fungus inside the insect.


Advantages :

• Under high humidity conditions it kills pupae and adult insects.
• The fungus possesses the high speed of growth, huge reproductive ability and high specificity;
• It is necessary to use the fungus several times until all the phytophages are killed on treatable area. If the pest regenerates its population treatments should be repeated.
• The first symptoms of fungus infection can be displayed on the whitefly in 7–10 days. After two weeks the effect of influence is expressed exactly.
• The effectiveness of this product depends very much on climatic condition (temp 15–20°c and relative air humidity of 80%), the methods of application and doses.
