Abstract Alternaria brown spot - ABS (Alternaria alternata) causes lesions on fruits, leaves and branches of mandarins. The cost fungicide application is high alternative managements for the control need to be studied. We aimed evaluate calcium (Ca) nutrition mitigate effects ABS. Murcott IAC 221 tangor plants were nourished with nitrate at three different concentrations (30, 150 300 mg Ca L-1)...

Northern Corn Leaf Blight (NCLB) is a foliar disease, caused by fungal pathogen (Setosphaeria turcica) that damages maize crop due to heavy losses in every year. A study was conducted for NCLB and identified quantitative trait loci (QTLs) maize. Mapping population F2:3 families developed involving two inbreds viz CM 212 (susceptible) & 145 (resistant).The mapping evaluated environments (BHU...

In Madura island, corn is the main commodity that widely planted with an area of 301,725 ha or about 30% maize in East Java. Island has local cultivars, such as: Tambin, Talango, Guluk-guluk, Manding, and Kretek. Efforts to increase production are continuously being made, starting from improving varieties until managing plant pests. One diseases downy mildew. However, information incidence, sev...

Brazil is the world’s largest producer of sugarcane (Saccharum officinarum), but occurrence and severity diseases such as orange rust (Puccinia kuehnii), ring spot (Leptosphaeria sacchari), red rot (Colletotrichum falcatum) could be part several factors limiting its production reason for replacing cultivars. It important to use other forms disease control depending on time required ob...

Cultivated American ginseng (Panax quinquifolius) is a perennial herb valued as traditional Chinese medicine. The crop commercially produced under polypropylene shade cloth, creating climate favorable for leaf blight caused by Alternaria panax; frequent fungicide applications are required annually to protect yields of the root and seed. Our objective was improve tactic identifying effective pro...

Vanilla is an economically important crop for low-lying humid tropical regions. World demand natural vanilla increasing, but cultivated plants face serious phytosanitary problems. The disease known as Fusarium wilt mainly related to the fungus oxysporum f. sp. vanillae, and its management, pathogen–host relationship must be understood. Four in vitro multiplied accessions were evaluated: two pla...

ABSTRACT Bacterial spot caused by Xanthomonas spp. (X. vesicatoria, X. euvesicatoria pv. euvesicatoria, perforans, and hortorum gardneri) may result in significant losses for tomato crops. Simonkolleite nanoparticles (SK-NPs) has been indicated as a novel approach plant disease control. The objective of this work was to evaluate SK-NPs (ZnOCl, ZnOCl:Ag, ZnOCl:Cu at different concentrations) the...

The soil-borne fungus Rhizoctonia solani causes damping-off on sugar beet seedlings. Growers rely fungicides to protect in fields affected by R. solani. Quinone outside inhibitor (QoI) fungicides, such as azoxystrobin, have been applied in-furrow and foliar sprays manage solani, but repeated use of QoI pose risks fungicide resistance. Penthiopyrad is a novel with the succinate dehydrogenase (SD...
