Trichoderma species are among important antagonists of plant pathogenic fungi. The main purpose of this study was to evaluate the biocontrol potential of native Trichoderma spp. isolates from sugar beet fields against Phytophthora drechsleri and P. cryptogea, the causal agents of Phytophthora root rot of sugar beet. During 2007–08, 85 isolates of Trichoderma spp. from sugar beet fields in eight...
This study aimed at analysing patterns of crop sequences over time throughout the German federal state of Lower Saxony from 2005 to 2012. Therefore, the IACS (Integrated Administration and Control System) data was analysed for the identification of spatial and temporal pattern of crops grown on farmer’s fields. Lower Saxony is a region where maize growing had a steep increase and, therefore, wa...
Sugar Beet Nematode (SBN), Heterodera schachtii, is one of the most destructive pests of sugar beets worldwide. It is present in all sugar beet growing areas of Wyoming and is particularly severe in fields located in close proximity to processing plants where sugar beets have been grown the longest.

The Farm Scale Evaluations of genetically modified herbicide-tolerant crops (GMHT) were conducted in the UK from 2000 to 2002 on beet (sugar and fodder), spring oilseed rape and forage maize. The management of the crops studied is described and compared with current conventional commercial practice. The distribution of field sites adequately represented the areas currently growing these crops, ...
This study was designed to evaluate selected chemical and microbiological treatments for the conversion of certain local agro-industrial wastes (rice straw, corn stalks, sawdust, sugar beet waste and sugarcane bagasse) to ethanol. The chemical composition of these feedstocks was determined. Conversion of wastes to free sugars by acid hydrolysis varied from one treatment to another. In single-st...
genus polymyxa, belongs to plasmodiophoromycota phyllum and protozoa kingdom. this fungus is a obligate endoparasite in the root cells of vascular plants. since the two species of this genus, p. graminis and p. betae are both known to carry destructive viral agents to sugar beet and poaceae. for studying the distribution of infected fields with p. betae in razavi and northern khorasan provinces...
sugar beet cultivation is of great importance in isfahan province. powdery mildew is a major limiting factor to sugar beet. to evaluate powdery mildew status in sugar beet fields, samples were collected from main sugar beet growing areas including, isfahan, semirom, farydan and komsheche during 2009-10. in order to determine the disease severity, in each region, samples were taken at six growth...
sugar beet is one of the major products in qazvin plain that allocated most of planting areas to itself after wheat, barley and corn. in recent years, restriction on water resources decreased sugar beet planting area in this plain. therefore, in this study, the effects of increase in sugar beet planting area on planting pattern, grower's gross profit, and inputs utilization under water sho...
