like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
Rhizoctonia root rot disease is considered as one of the important diseases in sugar beet. Using resistant cultivars decreses production costs, especially application of fungicides and increases the efficiency in controlling of root rot disease. Therefore, growing of resistant cultivars is considered the best approach for disease control. To achieve this goal and to determine yield potential of...
Comparison of Pratylenchus penetrans Infection and Maladera castanea Feeding on Strawberry Root Rot.
The interaction of lesion nematodes, black root rot disease caused by Rhizoctonia fragariae, and root damage caused by feeding of the scarab larva, Maladera castanea, was determined in greenhouse studies. Averaged over all experiments after 12 weeks, root weight was reduced 13% by R. fragariae and 20% by M. castanea. The percentage of the root system affected by root rot was increased by inocul...
American chestnut is one of hundreds of plant species plagued by root rot caused by Phytophthora cinnamomi. Phytophthora root rot is thought to have contributed to chestnut dieback prior to the arrival of chestnut blight, and it may now present a serious limitation to establishment of blight-resistant hybrid chestnut. We manipulated soil compaction and moisture to evaluate the effect of soil ph...
to study the effects of sowing dates, irrigation intervals and different cultivars on sugar beet root rot disease management and its quality and quantity yields, an experiment was conducted in a split- factorial based on randomized complete block design with four replications in the field of sugar factory jame. two irrigation intervals: eight days and 16 days were allocated in main plots, and d...
Ghaderi F, Hasehemi SAA (2022) Phytophthora citricola as the causal agent of persimmon root rot in Fars province of Iran. Plant Pathology Science 11(2): 1-10. Doi: 10.2982/PPS.11.2.1 Introduction: Phytophthora species are a serious threat to plant products worldwide. Therefore, identifying them is the first step in finding a way to treat the disease. The aim of this study was to identify ...
Pink root-rot disease caused by Pyrenochaeta terrestris is one of the serious diseases of onion fields in Iran and the world. The use of resistant cultivars might be a good alternative as suggested on the basis of the screening at the near end of growing season. The susceptibility assessment of 43 Iranian onion clones in glass-house condition in Isfahan for the last two successive years i.e. 20...

abstract common root rot induced by bipolaris sorokiniana, is one of the most important diseases of wheat. chemical control of this disease is difficult because of it is a soil-born pathogen, so that, application of other methods is useful to reduce disease level especially resistance cultivars. in this research, were examined reaction of some wheat cultivars and lines against common root rot i...
fusarium solani wasisolated from diseased roots of common bean (phaseolus vulgaris) grown in fields which were severely infected with fusarium root rot of bean in markazi province of iran. specific pcr primer pairs were used for the identification and verification of f. solani (mart.) f.sp. phaseoli (burkholder) w.c. snyder and n.h. hans. spore suspensions of f. solani f.sp. phaseoli were subje...
