The University of Arkansas has published its latest guide to diseases of tree and row crops ranging from apples to zucchini, including soybeans and rice. The 95-page guide, known officially as MP154, is available free for the download at www.uaex.edu.
With rice, for example, the guide provides disease-control measures from seed treatments to kernel smut and neck blast.
The soybean section addresses seedborne pathogens and continues through to foliar problems, such as soybean rust. It also contains a chart so you can compare efficacy of various products against specific diseases.
In addition, the guide contains information for cotton, wheat, corn, peanuts, vegetables, small fruit and tree fruit.
