"Efficacy evaluation of certain "bio" products on powdery mildew pathogens on tomatoes and melons in laboratory conditions". Lucrări Știinţifice USAMV – Iași Seria Horticultură, 60(1): 177-182.https://repository.iuls.ro/handle/20.500.12811/1336The purpose of this experimentwas to study the biological efficacy of "bio"products Mimoten 0.3% (80% Mimosa tenuifolia extract) and Zytron 0.15%(20% citric seeds extract), ontomatoes and melons against Erysiphe sp. and Sphaerotheca fuliginea, respectively. The experiments were carried out in "wet chambers" (in thermostat at 26± 20C and 60 -70% RH) on detached leaves with similarlevels ofthe attackdegreefrom tomato and melonsplants attacked by Erysiphe sp. on tomatoes and Sphaerotheca fuliginea onmelons. The combination of Mimoten 0.3% + Zytron 0.15% products had the best efficacy incontrollingof both pathogensErysiphe sp.on tomatoes(76.3%) and Sphaerotheca fuliginea on melons (65.4%).entomatoesmelonsErysiphe sp.Sphaerotheca fuligineatomatepepeni galbeniArticle2069-8275
