Field screening of safflower genotypes for resistance to charcoal rot disease
Nineteen safflower genotypes (Carthamus tinctorius L.) that originated from different geographical regions were screening for their response to infection with Macrophomina phaseolina, the charcoal rot pathogen at the research farm of Gorgan University of Agricultural Sciences and Natural Resources, Gorgan, Iran, in 2005. The plants were evaluated for length and width of necrotic lesion at the e...
متن کاملAvailable Methods for Assessing Varietal Resistance to Sugarcane Stalk Borers
Sugarcane is semiperennial and produces considerable biomass, forming an ideal habitat for insects. Most insects do not affect crops, but some compete with humans for sugar and by-products. Sugarcane stalkborers are key pests of this crop worldwide because they feed directly on the vegetative tissues that store sucrose, allowing the introduction of micro-organisms that affect yield and quality....
متن کاملPea aphid biotype performance on diverse Medicago host genotypes indicates highly specific virulence and resistance functions.
Aphid-plant interactions depend on genotypes of both organisms, which determine the two-way molecular exchange that leads to compatible or incompatible outcomes. The underlying genes are mostly unknown, making it difficult to predict likelihood of aphid success or host resistance, and hampering crop genetic improvement. Here we screened eight pea aphid clonal genotypes collected from diverse le...
متن کاملMarine Borers Resistance of Chemically Modified Portuguese Wood
An adequate service life of wooden structures in the sea is ensured only: If wood is treated with biocide wood preservatives with high retention level or; If some tropical hardwoods, with known natural resistance, are used. However, the poor public image of use the tropical hardwoods, as contribution to deforestation at one hand and legal requirements to restrict the use of biocide preservative...
متن کاملBio-Management of Plant-Parasitic Nematodes in Pigeon Pea Field Crop Using Neem-Based Products and Manurial Treatments
A field plots experiment was carried to investigate the influence of soil applications of neem-based (Achook and Nimbidin) and crop fertilizer (urea and cattle manure) treatments, separately and in combination on free-living and plant-pathogenic nematode populations and crop productivity. Data regarding the results showed that all the treatments significantly decreased the number of plant-paras...
