Late blight disease, caused by the plant pathogen , is one of the major threats for tomato and potato crops. Monitoring the populations of . is important to determine if there are changes in the sensitivity to fungicides and host preference.
View Article and Find Full Text PDF, the causal agent of late blight disease of potatoes, is mainly controlled by the use of fungicides. Isolates that are resistant to commonly used fungicides have been reported. Also, several studies show that originally mefenoxam-sensitive isolates acquire resistance to this fungicide when exposed to sublethal concentrations.

We present this information in the context of both historical and technological developments which can effectively be overlaid upon each other. We describe intrinsic anatomy and connectivity and then discuss early work which described how circulating angiotensin II acts at the SFO to stimulate drinking and increase blood pressure.

Thirty-six isolates, collected from southern Colombia between 2008 and 2009, were used to inoculate common tree tomato cultivars, Común, Híbrido, Injerto, and Holandés.

Thus, we investigated variation among individuals of for relative growth at different temperatures.
