Impact of Nano-Technology in Enhancing Nematode Biocontrol Efficiency Via Jojoba Oil and Maintaining Root Environment

Abstract

In a greenhouse belong to Pomology Department, National Research Centre, Cairo, Egypt conducted the present work during 2022/2023aims of this study was to investigate the effect of nanotechnology on improving the efficiency of jojoba oil biological control of nematodes and root environmental protection. The investigated concentrations of treatments were divided into 5 groups (Control, Starkim, Jojoba 10 ml, Nano emulsion 5 ml and Nano emulsion 7 ml). The results obtained for both seasons showed that concentrations of Jojoba oil and Nano Jojoba oil (7ml/l) compared to the control and starkim group. However, the highest values apply to fresh weight, dry weight and water content as a result of Jojoba oil and Nano Jojoba oil (7ml/l). However, jojoba oil treatment both (original and nanoemulsion) surpassed control and starkimin nutrient uptake then followed by nano-emulsion of jojoba at 5ml/l. On the other hand, a positive correlation between Jojoba oil (crude and Nano-emulsion) on nematodes population, highest reduction percentages observed with strakim, nano-emulsion jojoba oil and crude jojoba oil, respectively. Moreover, jojoba oil applications more effective in reducing of galls on root than starkim. Results revealed that the reduction percentages of egg mass obtained by crude
Jojoba oil at 10ml/l followed by nano-emulsion of Jojoba oil at 7 ml/l. Besides, for soil microbial activity treating with jojoba oil resulted in encouraging most studied growth performance parameters of infected grapevine with nematode. This study concluded that using nano-emulsion of these oils (Jojoba oil with 7 & 5%) can be used as effective alternative to commercially available formulation on
nematode control, and eco-friendlier.
