The culture filtrate significantly reduced B. cinerea growth by 94.6, and 73.7% at concentrations of 70, and 60%, respectively. Moreover, the culture filtrate of T. reesei at 70% concentration caused an enormous reduction in incidence and severity of the disease by 80.5, and 90.5% in comparison with the untreated group respectively.

Sublethal concentrations (LC 25 ) of the tested agents against adult females of T. urticae were determined using standard bioassay procedures. The effects of sublethal concentrations of the investigated compounds on egg deposition and egg hatchability were measured over five days at 22 and 28 degrees Celsius, respectively. The effects of the investigated substances on the duration (in hours) of T.urticae developmental phases were evaluated at two different temperatures 22 and 28 o C. The results showed that silica nanoparticles (NPs) coated with abamectin had a significant influence on egg deposited decrease by T. urticae adult females. By the way, silica NPs-abamectin was the most effective therapy for egg deposition and hatchability over five days at 22 and 28 o C respectively, followed by abamectin. Furthermore, silica NPs-abamectin was found to be very beneficial in prolonging the length (in hours) of T.urticae developmental stages at different temperatures.
