Abstract

Field experimented were examined the effects of Piper nigrum and Urtica dioica extracts on the gray mold disease in tomato that caused by Botrytis cinerea. To evaluate the inducing resistance of these extracts, many treatments were sprayed on tomato leaves, including methanolic and aquatic extracts, Silver nano particles biosynthesis (AgNPs) and water as (control). The results indicated that the resistance of tomato plants was increased when tomato plant sprayed first with Methanolic P. nigrum extracts and after 4 hours sprayed with B. cinerea. Also, spraying with methanolic and aquatic AgNPs P. nigrum extract were reduced gray mold disease. These results were showed that P. nigrum AgNPs treatment reduced the gray mold of tomato leaves because of the activities of total phenolic compounds which was infected with Botrytis cinerea.

Summary

Introduction

‫الديطرة على مرض العفن الرمادي على نبات الطماطة برشها بمدتخلص الفلفل الاسود والق ارص تحت‬ ‫ظروف البيت الزجاجي‬. Spraying with methanolic and aquatic AgNPs P. nigrum extract were reduced gray mold disease. These results were showed that P. nigrum AgNPs treatment reduced the gray mold of tomato leaves because of the activities of total phenolic compounds which was infected with Botrytis cinerea. This work was conducted to evaluate the effect of spraying black pepper (Piper nigrum) and Nettle (Urtica dioica) (Methanolic and Aqueous) extracts with and without silver nanoparticles (AgNPs) on suppressing the development of the tomato gray mold disease.
