Determination of Giftii Bio Pesticide Rate for the Control of Fussarium Head Blight Disease of Wheat in Arsi Area

The average national yield of wheat is about 2.8 t/ha. However, poor yields are partially attributed by losses from Fusarium head blight (FHB), Septoria Spp, and rust diseases three main biotic threats to wheat productivity in Ethiopia and around the world. These losses are made worse by climate change, and a sizable amount of wheat which makes up 9% of the country's total cereal production is imported annually to make up the difference. In order to control FHB in wheat-potential areas in 2022 and 2023, the trial seeks to ascertain the proper rate of new product (GBP). Fertilizer application, weed control, and planting at the suggested seed rate were all part of the trial. Plant surfaces were treated with a mixture of test bio pesticides and a check fungicide and tap water. Grain yield, HLW, and TKW were measured, and bleached spikes were used to gauge the severity of the disease. In Kulumsa, Fusarium head blight (FHB) was shown to be more severe over the course of two years in the trial field. The productivity of sensitive cultivars Boru demonstrated higher yield with various treatments of G_BP and standard check Nativo 300Sc compared to untreated plots. The study also looked at the effect of G_BP on other agronomic variables. In terms of grain yield, weight of thousand kernels, and floor contents of Boru, the results indicate that 1liter/hectar of G_BP bio pesticides are comparable to standard check Nativo 300Sc. At 5% degree of freedom, however, they differ considerably from the untreated plot and are not significant from standard check.
