Few strains of Metschnikowia pulcherrima (Pitt) M.W. Miller are under development for control of postharvest pathogens on fruit. A substrate was developed to optimize the biomass production of M. pulcherrima strain BIO126. Different complex nutrient sources, with or without pH control, were tested. Growth in yeast extract provided at concentrations > or =30 g*L-1 yielded the highest biomass. Th...

Phytophthora root rot, caused by nicotianae Breda de Haan, is one of the destructive diseases boxwood ( Buxus sempervirens L.) and can affect all growth stages field- container-grown plants. Management a problem only possible through an integrated approach. In this study, efficacy fungicides, biofungicides, host-plant defense inducers, fertilizer were evaluated to manage rot boxwood. The object...

Abstract Background Safe food free from diseases is the world's goal. Excessive usage of chemical fungicides considered most important danger for climate. Natural alternatives with low costs have become best choice sustainable agriculture. Results In context researching green materials instead fungicides, fabrication nano- Sargassum vulgare and its composite zeolite was carried out. Followed by...

To develop a commercial product using the mycoparasitic fungus Simplicillium lamellicola BCP, the scaleup of conidia production from a 5-l jar to a 5,000-l pilot bioreactor, optimization of the freeze-drying of the fermentation broth, and preparation of a wettable powder-type formulation were performed. Then, its disease control efficacy was evaluated against gray mold diseases of tomato and gi...

Sweet chili pepper (Capsicum chinense Jacq.) is an important part of the local cuisine Puerto Rico where it known as ají dulce. Considering opportunities for vegetable production in Rico, soilless alternatives sweet should be considered. This study evaluated five substrates: (1) PRO-MIX® BX (BX); (2) + Mycorrhizae (BX+Myco); (3) High porosity (HP+Myco); (4) Biofungicide (HP+Myco+Fung); and (5) ...

Macrophomina phaseolina é um fitopatógeno de solo com ampla distribuição geográfica, responsável por ocasionar perdas econômicas graves incitando sintomas podridões no sistema radicular e caule das plantas infectadas. Há uma demanda mundial crescente novos tratamentos, que promovam a segurança alimentar nutricional, substâncias mais eficazes menos danosas ao equilíbrio dos ecossistemas. O objet...

Japanese-cedar [Cryptomeria japonica (L.f.) D. Don] represents an alternative to leyland cypress [·Cuprocyparis leylandii (A.B. Jacks. & Dallim.) Farjon] as an evergreen screen or specimen plant for landscapes. It performs well under a range of soil and environmental conditions but has been underused attributable, in part, to unsightly winter browning caused by photoinhibition. In previous stud...

In an effort to develop an alternative to methyl bromide-dependant strawberry (Fragaria x ananassa Duch.) field production in north-central Florida, we evaluated various soilless substrates, growing containers, plug transplants, plant densities, cultivars, and biological control strategies in a passively ventilated high-roof greenhouse near Gainesville, Florida. The type of soilless media used ...
