An increase in the concentrations of water-insoluble iron phosphate (Fe-P) compounds in acidulated P fertilizers has raised the concern that the agronomic effectiveness of these P fertilizers will decrease. This study was conducted to evaluate the ag

Race 2 of Fusarium oxysporum f. sp. niveum overcomes all current wilt-resistant watermelon cultivars. In previous studies, resistance to race 2 was induced in the greenhouse by prior inoculation with avirulent races (races 0 or 1) or with the cucumbe
