The Biology, Ecology, and Control of Sclerotium Rolfsii
- Z. Punja
Since the comprehensive review by Aycock in 1966 (15), numerous papers on various aspects of the biology and ecology of the soilborne plant pathogen Sclerotium rolfsii Sacco have been published, and… Expand
Seaweed extract reduces foliar fungal diseases on carrot
Abstract Greenhouse-grown carrot plants were sprayed with an extract (0.2%) of the seaweed Ascophyllum nodosum (SW) and then inoculated 6 h later with the fungal pathogens Alternaria radicina and… Expand

ABSTRACT Dramatic changes occurred within populations of Phytophthora infestans in the United States and Canada from 1994 through 1996. Occurrence of the US-8 genotype, detected rarely during 1992… Expand
Metabolic engineering of novel ketocarotenoid production in carrot plants
Carotenoids constitute a vast group of pigments that are ubiquitous throughout nature. Carrot (Daucuscarota L.) roots provide an important source of dietary β-carotene (provitamin A), α-carotene and… Expand
Using fungi and yeasts to manage vegetable crop diseases.
Vegetable crops are grown worldwide as a source of nutrients and fiber in the human diet. Fungal plant pathogens can cause devastation in these crops under appropriate environmental conditions.… Expand
Altered root exudation and suppression of induced lignification as mechanisms of predisposition by glyphosate of bean roots (Phaseolus vulgarisL.) to colonization byPythiumspp.
Abstract Several possible mechanisms for the glyphosate-induced predisposition of bean roots ( Phaseolus vulgaris L.) to colonization by Pythium spp. were investigated. Glyphosate at 0.1 and 1.0 μg… Expand
Commercial extract from the brown seaweed Ascophyllum nodosum reduces fungal diseases in greenhouse cucumber
This study examined the effects of Stimplex™, a marine plant extract formulation from Ascophyllum nodosum, on some common cucumber fungal pathogens. Greenhouse cucumber plants were sprayed and/or… Expand
Efficacy of Biological and Chemical Treatments for Control of Fusarium Root and Stem Rot on Greenhouse Cucumber.
Potential disease control methods were evaluated against root and stem rot of cucumber (Cucumis sativus) caused by Fusarium oxysporum f. sp. radicis-cucumerinum. Crab/shrimp shell chitin; three… Expand
Combined expression of chitinase and lipid transfer protein genes in transgenic carrot plants enhances resistance to foliar fungal pathogens
Two pathogenesis-related (PR) protein genes consisting of a barley chitinase (chi-2) and a wheat lipid-transfer-protein (ltp) were introduced singly and in combination into carrot plants via… Expand
Tissue culture and Agrobacterium-mediated transformation of hemp (Cannabis sativa L.)
SummaryHemp (Cannabis sativa L.) is cultivated in many parts of the world for ils fiber, oil, and seed. The development of new hemp cultivars with improved traits could be facilitated through the… Expand
