The soilborne pathogens Rhizoctonia solani, Pythium ultimum, and Meloidogyne incognita can cause severe economic losses to fieldand greenhouse-grown cucumber. A collection of bacterial isolates and isolates GL3 and GL21 of Trichoderma virens were screened for suppression of diseases caused by these pathogens. T. virens isolates GL3 and GL21 provided the most effective suppression of damping-off...

Exposure to bioaerosols in occupational settings is associated with a range of adverse health effects. The aim of this study was to investigate the exposure levels to dust and endotoxin of people working in two cucumber nurseries and two tomato nurseries. Exposure was measured for greenhouse workers (n = 70) mainly working on harvesting cucumbers and tomatoes and clearing the plants after the h...

abstract soilless culture of greenhouse vegetables has been a fast developing section in iran during recent years. most growers use hydroponics systems with artificial substrates. some of the used substrates have low water retention which results in wasting a great deal of solution. on the other hand, low vigor of cucumber root in water and fertilizer absorption, especially in low media tempera...

ABSTRACT Plant growth-promoting rhizobacteria (PGPR) strains INR7 (Bacillus pumilus), GB03 (Bacillus subtilis), and ME1 (Curtobacterium flaccumfaciens) were tested singly and in combinations for biological control against multiple cucumber pathogens. Investigations under greenhouse conditions were conducted with three cucumber pathogens-Colletotrichum orbiculare (causing anthracnose), Pseudomon...

Fertigation systems, especially hydroponic systems with recirculating nutrient solution, are an ideal environment for algal growth, but it is not clear if this contaminant affects the crop. Therefore, greenhouse experiments were carried out to monitor the development and composition of algae, as well as their effects on lettuce and cucumber performance. In addition, several different substrates...

In this study, antifungal activity of essential oils of Cymbopogon citratus and Ocimum basilicum and two fungicides Mancozeb and Metalaxyl-Mancozeb in six different concentrations were investigated for controlling three species of Phytophthora, including P. capsici, P. drechsleri and P. melonis on pepper, cucumber and melon under in vitro and greenhouse conditions, respectively. Under the in vi...

Virus diseases are the major cause of economic losses in commercial cucurbit production in Lebanon. Besides mosaic inducing viruses, which have been noted for several years, greenhouse-grown cucumber and melon were often observed with severe yellowing symptoms that started as interveinal mottle on the older leaves and developed into severe yellowing symptoms as the leaves became older. The inci...

Salicylic acid (SA) is a phenolic compound capable of inducing physiological and metabolic changes that enhance the tolerance plants to saline stress associated with using hydroponic system enable use water in semi-arid regions. In this context, assay aimed evaluate impact foliar application SA on mitigating salt effects Japanese cucumber cultivated system. The experiment was carried out protec...
