Short history of Bioceres® WP
25 years ago, Ph.D. student of Biology and Environmental Sciences Silvia Todorova was inspired by the idea of creating a Bio-insecticide made from a Quebecer strain of Beauveria bassiana, a fungus capable of infecting and killing certain type of pest-insects. In fact, it was a strain of Beauveria bassiana, the strain ANT-03, isolated from an Tarnished plant bug (Lygus lineolaris) in Montreal, the one chosen to be the main ingredient of this innovative product.
Several years of hard work and continuous research and development allowed this ambitious project to become a reality. Finally, introducing to the world The BioCeres® WP. This powerful product was named after the roman deity of agriculture “Ceres”.
Highlights of Bioceres® WP
- 2005 — Creation of Anatis Bioprotection. The Beginning of research and development of BioCeres WP®.
- 2014 — Frist batch of product released into Canadian agricultural market targeting aphids, white flies and thrips in tomato, cucumber and greenhouse ornamental plants a.
- 2015 — BioCeres® WP obtained the Organic EcoCert certification.
- 2016 — BioCeres® WP was introduced to the American market by BioSafe Systems
- 2017 — At present we are waiting for registration to use BioCeres® WP in herbs and spices, medical cannabis and sweet potatoes in greenhouse.
Another 5 registration demands have been submitted in Canada
- Against Tarnished plant bug in strawberries and raspberries.
- Against Colorado potato beetle (Leptinotarsa decemlineata) in potato.
- Against Hairy chinch bugs (Blissus leucopterus hirtus) in grass.
- Against Grub worms in grass.
- Against Emmerald ash bores (Agrilus planipennis).
BioCeres® WP mode of Action
First, the spores of Beauveria bassiana adhere to the insect cuticule (skin)and then, they penetrate it. Later, the spores grow until they reach the insect’s hemolymph (blood). There, they feed from it, causing the death of the insect after 7 to14 days. Under certain conditions it is possible to observe the fungus spore’s development outside of the insect giving to it a whitish appearance. This is characteristic of Beauveria bassiana presence.
Excellent growth rate under proper conditions
According to the Scientific Director of the Bio-insecticide Division at Anatis Bio-protection, Martin Nadeau, B. bassiana has an optimal growth temperature of 25 ºC (77 ºF) and its spores require more than 60 % of humidity to germinate. Temperatures lower than 15 ºC (59 ºF) slow spore’s growth while temperatures higher than 33 ºC (92 ºF) inactive them. Literature indicates that B. bassiana can growth in a wide range of pH, however, its optimal is 5.6 ± 0.2.
A bio-insecticide with a good shelf life
BioCeres® WP may be stored during a period of 12 months at 4 ºC (40 ºF) or 6 months at 21 ºC (70 ºF). Nonetheless, if storage conditions are not respected (time and temperature), germination can be affected and therefore, product’s efficiency.
No phytotoxic and safe for human’s health
BioCeres® WP does not represent a risk for plants and no cases of insect’s resistance has been observed. This product is safe for humans (re-entry 0 day) and reduces the exposure of producers, workers and consumers to chemical products. It is compatible with certain fungicides and most of insecticides and beneficial insects.
Spores are affected by UV light; thus, the product should be administered at late afternoon or night, when environmental conditions favor the fungus growth (low UV light and high moisture).
BioCeres® WP is a product with highest standards of quality
Provide products of high quality is one of our most important commitments. Our microbiology team oversees the quality of every single batch of product guaranteeing the infectious efficiency of the B. bassiana spores.
Each year, our team together with agricultural producers and research centers conduct field experiments with the product against different plant pests. This allows to document the effects of broadening product’s action spectrum.
Predatory Mites used as B.bassiana carrier, a promising solution
In collaboration with Gongyu Lin a Ph.D student from Montreal University. We evaluate the use of predatory mites as carriers of B.bassiana spores. We believe that these methods combine may increase fungus dispersion even in spots difficult to reach by spraying (e.g inside of the flowers).
Additionally, after some days, the weakest mites will not survive the long exposure to the fungus. They will act as a little Kamikase. These time bombs will become new infectious agents after their death.
