Agricultural crops are exposed to numerous fungi and other sources of disease that can destroy crops in the field. Researchers at Syngenta have developed in-field diagnostic tests for crop disease to help farmers properly identify and treat problems as early as possible. Scientists are also exploring ways to insert new genes into specific crops to give immunity to key plant diseases, which can also improve the quality of the products. Effective insect control can even help contribute to improved disease control by decreasing insect damage to plants which can often serve as an entry for other types of plant diseases. This multi-tiered approach holds the promise of more effective control of plant diseases in the future.
