Assessment of the efficacy of garlic (Allium sativum L.) extract for the control of Aspergillus flavus and other fungi on maize seeds in North central, Nigeria.

This study was carried out to evaluate the antifungal activities of aqueous extracts derived from garlic (Allium sativum L.) aqueous extract on maize seed-borne fungi with emphasis on Aspergillus flavus. A total of 114 samples of rot-infected unshelled maize cobs were collected from three States and the Federal Capital Territory (FCT), Abuja in the North Central zones of Nigeria. After shelling and bulking, the fungal load and molecular identification of Aspergillus flavus isolated from samples were determined. Thereafter, one set of 200 g seed portions from the samples were treated with aqueous garlic extract while the other set were left untreated before being stored in propylene bags for four months. Then, using agar plate method, fungal load and radial growth inhibition of the A. flavus and other fungi by garlic extract were determined. The study revealed that the incidence of A. flavus isolated from the maize grains samples from the FCT, Abuja and Benue State were significantly higher (p≤ 0.05)  than those from other two states. Out of the five suspected pure A. flavus isolates sent for molecular identification, four of them were duly identified as A. flavus. It was confirmed from the treated stored maize seeds that garlic extract significantly inhibited (p≤ 0.05) Aspergillusflavus, with radial growth reduced by 59.05%.  The findings can serve as basis for developing an organic agricultural compatible garlic-based management strategy for maize rot fungi complex.
