ProChip Soil Insecto

ProChip – Insecto contains fungi Beauvaria Bassiana in spore form 2.5X109 cfu/gr (Organic Insectides).

Mistakes in using chemical for pests and deases controll caused soil toxicity and ecologycal imbalance. This is the main factor which responsible for pests and diseases vulnerability and variability. Ecological engineering by using organic pesticides, develop natural enemies of pests and diseases, light traps, Pheromones, environment and ecological management, are FAO recommendations and shoud be promoted intensively.

Beauveria Bassiana General Information

Beauveria bassiana, formerly known as Tritirachium shiotae, is an entomopathogenic fungus (parasitic to insects) that grows naturally in soils throughout the world. It acts as a parasite on a very wide variety of arthropods, including, whiteflies, termites, thrips, aphids, beetles,caterpillars, weevils, grasshoppers, ants, mealybugs, bedbugs and even malaria-transmitting mosquitoes. Insects vary in susceptibility to different strains. Strains have been collected from different infected insects and cultured to create a particular product for commercial use. The product is made via a bio-fermentation process. The spores (conidia) are extracted and made into a sprayable form. Beauveria bassiana was named after the Italian entomologist Agostino Bassi. He first found B bassiana in 1835 as the cause of the muscardine disease of the domesticated silkworms.

Beauveria Bassiana Mode of Action

Beauveria bassiana kills arthropods as a result of the insect coming into contact with the conidia (fungal spores). Contact is made in several ways. The most common and effective is the spray droplets landing on the pest or by walking on a treated surface. Once the fungal spores attach to the insect’s cuticle, the fungus spores germinate sending out threaded hyphae which penetrate the insect’s body and proliferate. It takes 3 to 5 days for an infected insects to die. The dead insect may serve as a source of spores for secondary spread of the fungus. An infected adult male will also transmit the fungus during mating. (Long et al. 2000).

Beauveria Bassiana Mode of Application

The liquid spray should have a concentration of at least 2.5X109 viable spores. High humidity and water amplify the activity of the conidia and the infection. Fungal spores are readily killed by solar radiation. It is best to spray the plants with the anthropoid pests in the morning or late afternoon, in cool to moderate temperatures (Goettel et al. 2000, Wraight and Ramos 2002). Apply the Beauveria bassiana liquid spray to the top, as well as the undersides of the leaves, or wherever the arthropod primarily occurs. Good coverage is a must. The spores have a relatively short life cycle, so it is important that the spray has sufficient opportunity to contact the insect. For insects that bore into a plant, control is difficult. For the best results, applications should be made during the early growth stages of the insect before much damage has occurred. The speed of kill depends on the number of spores contacting the insect, insect age, susceptibility and environmental conditions.
