This study was performed to investigate the inhibitory effect of green onion produced in Korea on the growth of A. parasiticus, a toxigenic strain. The effect was studied using different concentrations of freeze-dried green onion in solid culture with potato-dextrose agar (PDA) or in liquid culture with yeast-extract sucrose (YES) broth at 25°C for 15 days. The addition of green onion to the me...

Fusarium solain is the most important pathogen of huge range of plant hosts, especially potato in the word, which causes tuber rot in storage and root rot of potato plants in fields. Fifty four isolates from potato, bean, chickpea and cucurbit (melon, watermelon and cucumber) was subjected in a study through analysis of vegetative compatibility groups (VCGs) and rep-PCR DNA fingerprinting. Nit ...

: fried products derived from potato, particularly potato crisp have been widely included in food basket of the households in the recent years in iran. potato crisp, among other products, is of great importance and is considered as competitive products. this product is in the list of the food products with high acrylamide content. therefore, due to the nutritional importance of this product and...

J. Econ. Enlomol. 74: 30}-308 (1981) Larvae and adults of Phthorimaea operculella (Zeller) in potato foliage were effectively controlled by commercial applications of azinphosmethyl and a combination of methomyl and methamidophos, but eggs and pupae were not significantly affected. Azinphosmethyl, methomyl, and methamidophos provided adequate control of foliar larval populations, but larval par...

Sweet potato has been identified as a crop that has great potential for alleviating food security concerns (28). However, because it is vegetatively propagated, it is prone to accumulate viruses and other pathogens. Sweet potato viruses are difficult to transmit mechanically, they occur in mixed infections, and their host range often is restricted to the family Convolvulaceae (24). These factor...

We define a “hot potato” to be an exchange good which may be traded a finite number of times, and which becomes a bad if and when it can no longer be exchanged. Under standard assumptions of rationality and common knowledge, it is easy to show that no rational actor would freely accept a hot potato good, irrespective of the magnitude of the good’s exchange payoff or its last-holder penalty. Bou...

In comparison to single infections, co-infection of Nicotiana benthamiana with Potato virus X (PVX) and Potato virus Y (PVY) or Plum pox virus (PPV), resulted in increased systemic symptoms (synergism in pathology). Previous studies have shown that virus infections affected the accumulation of various microRNAs (miRNAs) and miRNA target genes. Our studies revealed that double infection by PVX a...

An, L.V., 2004. Sweet potato leaves for growing pigs: Biomass yield, digestion and nutritive value. Doctor’s dissertation. ISSN 1401-6249, ISBN 91-576-6750-0 The aim of the present studies was to evaluate the potential of using sweet potato leaves (Ipomoea batatas (L.) Lam) as a protein source in diets for growing pigs. A number of sweet potato varieties were evaluated with respect to the bioma...

Chromosome pairing relationships within cultivated potato (Solanum tuberosum) and its wild tuber-bearing relatives (Solanum sect. Petota) have been interpreted by genome formulas, developed in the early 1900s, through techniques of classic meiotic analysis of interspecifi c hybrids. Here we reexamine potato genome hypotheses with the fi rst phylogenetic analysis of all major genomes of sect. Pe...

agricultural training centres (atcs) promote crop and livestock development by providing extension information to farmers and serving as models of improved crop and livestock husbandry practices. although potato farmers in nyandarua county were trained on potato production technologies, their average yield was ≤16 tonnes per hectare compared to the national potential of 30 tonnes. this study th...
