Abstract

Two faba bean (Vicia faba L.) cultivars namely Giza 716 and Giza 40 were investigated for their response to foliar application with some botanical extracts and salicylic acid to improve vegetative growth, yield, and its relation to chocolate spot disease caused by Botrytis fabae Sard. Garlic cloves (GE), onion bulb (OE), eucalyptus leaves (EE) extracts (50 and 100 ml/L) and salicylic acid (SA 100 and 200 ppm) were used during two successive seasons of 2017/2018 and 2018/2019 at Etay El-Baroud Agricultural Research Station Farm, El-Beheira Governorate. Under field conditions Giza 716 had better values of growth, agronomic parameters and higher leaves content of chlorophyll a, b, (a+b), seed content of total carbohydrates %, protein %, leaves peroxidase and catalase activities and total phenols in both seasons. GE, OE, EE and SA increased faba bean growth and yield compared to Mancozeb and control treatments. SA 200 ppm increased leaf area /plant after 95 days in the first season. It had the first grade of shoot dry weight after 75 and 95 days and seed weight/plant in the second season and increased leaf area /plant after 75 days, plant height, number of branches/plant, number of pods/plant, 100 seed weight and seed yield/fed in both seasons. It increased chlorophyll a in the first season, chlorophyll b in the second season and chlorophyll a+b in both seasons. As well as, it had the highest catalase activity, total phenols content and protein %. In this respect, GE 100 ml/L significantly increased shoot dry weight /plant after 75 days and leaf area/plant after 95 days in the first and second seasons, respectively. It significantly increased shoot dry weight/plant after 95 days and seed weight/plant in the first season only compared to Mancozeb and control treatments. B. fabae spore suspension was applied using two techniques; foliar spray and droplet on leaflets.  Using detached leaf test in the laboratory, Giza 716 had lower disease severity % (DS %) and spot diameter than Giza 40. In case of spore suspension foliar spray technique the treatments of GE 100 ml/L, SA 200 ppm and Mancozeb had the least DS %.  In case of spore suspension droplet technique the treatments of OE 50 and OE100 ml/L and Mancozeb had the least spot diameter values. Under field conditions, disease severity increased with increasing periods from 75 to 105 days. Giza 716 had the lower DS % after 75, 90 and 105 days from sowing in both seasons than Giza 40. SA 200 ppm and OE 100 ml/L had the lowest DS % values in the first and second seasons, respectively.
