| Abstract | ||
| In laboratory study two formulation of Baculoviruses Spodoptera littoralis nuclear polyhedrosis viruses (NPVs) and Pthorimaea operculella granulosis virus (GVs) were produced in Egypt. Formulation of Baculoviruses, like chemical insecticides, is essential for consistent and effective control. Formulation additives such as wetting and thickening, and anti-evaporation agents were added to improve physical performance by aiding dispersion and suspension of the virus in the spray liquid, to improve the deposition of the virus spray and to aid the spread of spray droplets on the target. Many additives many also be included in a formulation to maximize persistence (e. g. Stickers, U V protectants) and to encourage ingestion of the viruses or to improve its potency. Finally with liquid concentrates of virus antibacterial and anti-fungal agents were added to prevent growth of contaminant microorganisms. Moreover, the goals required for a formulation, is to ensure their length of persistence. | ||
