ACR Vol. 02 - Elzein, Abuelgasim E.M.: Developement of a Granular Mycoherbicidal Formulation of Fusarium oxysporum „Foxy 2“ for the Biological Control of Striga hermonthica (Del.) Benth

Developing a formulation of microbial weed control agents is very essential for their storage, ease of application and protection against environmental constraints. Fusarium oxysporum “Foxy 2” is a fungal antagonist of Striga hermonthica, a root parasite of cereal crops that constitutes a major biotic constraint to food production in the Sahelian and the Savannah zones of Africa.

This book presents a detailed host range study, strategy of developing inoculum mass production techniques using inexpensive locally available agricultural by-products and a simple concept and technology for a biodegradable granular formulation. By adopting “Pesta” formulation technology, a dramatic reduction in the required end-use dosage of fungal inoculum could be achieved, offering a significant economical practical possibility for large scale application. Storage conditions for long shelf-life of Foxy 2 “Pesta” products were optimized as well. Valuable suggestions are also made for research to further enhance the efficacy of the products, as well as to improve the delivery of the mycoherbicide using seed treatment technology. The book intends to contribute to a more meaningful application of Foxy 2 as potential mycoherbicide against Striga within an integrated control approach adoptable and acceptable to subsistence farmers.
