“…Aplicação única de KCl na concentração de 0,1 M em folhas inferiores de pepino (Cucumis sativus) induziu resistência sistêmica nas folhas superiores contra Sphaeroteca fuliginea, por um período de 25 dias (Reuveni et al, 1994). Cloreto de potássio a 0,1 M também induziu RSA em plantas de milho (Zea mays) reduzindo em 80% a incidência de Puccinia sorghi, 10 dias após a inoculação (Reuveni et al,1996).…”

A indução de resistência sistêmica adquirida em plantas (RSA) constitui uma alternativa tecnológica bastante promissora para o controle de fitopatógenos. RSA se caracteriza pela ativação de mecanismos de resistência poligênicos latentes nas células vegetais, capazes de proteger plantas contra fatores bióticos e abióticos em parte ou em todo o seu ciclo vegetativo. Com o objetivo de identificar moléculas com capacidade indutora para o controle da vassoura-de-bruxa (Moniliophthora perniciosa) do cacaueiro (Theobroma cacao) foram testadas substâncias metabolizáveis pela planta e de impacto ambiental praticamente nulo. No experimento 1, plantas adultas do clone ICS 1, susceptível à vassoura-de-bruxa, foram submetidas, em uma única aplicação, a injeção no tronco de 20 mL de diferentes indutores. O experimento teve 12 tratamentos dos quais três foram controles, glicose

“…Potassium salts (K 2 HPO 4 or KNO 3 ) as a chemical agent for induction of plant resistance had great attention in many of these reports [4,5]. In this concern, spraying cucumber plants with K 2 HPO 4 induced resistance against downy and powdery mildews and increased fruit yield per plant under commercial greenhouse conditions [22,23,24,25,26]. Furthermore, there has been considerable interest in the use of sodium bicarbonate, potassium bicarbonate and potassium phosphate for controlling various fungal diseases in plants [22,23,27,28,29].…”

Furthermore, there has been considerable interest in the use of sodium bicarbonate, potassium bicarbonate and potassium phosphate for controlling various fungal diseases in plants [22,23,27,28,29]. Spraying plants with either sodium bicarbonate or potassium bicarbonate solution provided good control of several plant diseases [26,29,30].…”

Severe outbreaks of stem or fruit rot symptoms with sclerotial formation were observed as first occurrence during a disease survey of cucumber and pepper crops during the cool season, 2011 in the Protected Cultivation Station, Ministry of Agriculture located at Tookh province, Qalubiya governorate, Egypt. This disease appears during the growing season at the seedling or mature stages of plant growth. Recently, interest has been shown in combining microbial biocontrol agents with other chemical components to increase their activity against plant pathogens. To reach the proposed aim determination of the efficacy of some plant-derived essential oils, plant resistance inducers and plant extracts in combination with biocontrol agents against the growth of Sclerotinia foliage blight pathogens S. sclerotiorum and S. minor was carried out under in vitro conditions. The obtained results in the present study has shown the potential of tested materials as effective inhibitors against pathogenic fungi when combined factors with antagonistic bioagents.

“…Also, increased accumulation of peroxidase in phosphate treated leaves is strongly indicate the possible role or peroxidase in defense mechanism (Gamil 1995;Reuveni et al, 1995 andAbdEl-Sayed, 2000). Orober et al (1998) recorded that the foliar application of phosphate induced systemic acquired resistance in cucumber against powdery mildew (Sphaerotheca fuliginea).…”

“…Also, it has been reported that some phosphate salts induce systemic resistance against various pathogens including powdery mildew of cucumber (Reuveni et al, 1993 andReuveni et al, 1995). Salicylic acid was used by many researchers to study their effect as chemical agent for induce plants resistance against many pathogens (Zeier, et al 2004).…”

Effect of two types of vegetable oils (neem and soybean), two types of plant extracts (bougainvillea blossoms and Garlic), KH 2 PO 4 and salicylic acid (SA) as inducers and Eminent fungicide on sugarbeet powdery mildew disease, were tested to study their effect in vitro and in vivo against Erysiphe betae the causal pathogen of Sugarbeet powdery mildew. The reduction of spore germination was increased with concentration increasing in vitro. Most effective concentration was studied on powdery mildew disease of three varieties of sugar beet in greenhouse, all treatments had a significant effect in reducing disease severity compared to control Untreated plants, bougainvillea blossoms extract and Eminent fungicide were the most effective treatments. Enzymes, phenols, sugars, proteins and chlorophyll contents of leaves were evaluated. Bougainvillea blossoms extract exhibited high contents of sugars, phenols, protein, pigments and antioxidant enzymes.
