A plant that deviates from its normal growing pattern can be described as ‘diseased’. Many factors contribute to the growth of plants and this need to be taken in account when diagnosing a problem. Depending on the nature of the causal factors, diseases can be classed as ‘infectious’ or ‘non-infectious’. Live organisms or pathogens cause infectious diseases whereas unfavorable growing conditions cause non-infectious diseases.


We are working on the contents of the crop pest pages. For now, some plant disease images are listed below for viewing to give you an idea of what is to come. This section will contain the most important plant disease images per specific crop that cause production loss in agriculture. The most common plant diseases that can be found on most grain, legume, and oilseed crops, as well as vegetables, ornamentals, soil and lawn will be covered on these pages. If any person or company like to make a contribution to these pages please feel free to contact us at .


Please be patient while we are working on this section of the BCH website
