Types of RIZ, their content and application

There are many different types of RIZ:

**1.** **Rhizoctonia** are fungi that attack the roots of most types of agricultural crops, including such important ones as wheat, barley, corn, soybeans, rice, sunflower. **2.** **Corn cob lentiriosis** is a fungus that causes damage to the cobs, significantly reducing the yield of corn and impairing its quality. Symptoms of diseases caused by RRIs are divided into three groups: - **external (morphological)** - external manifestations of RRI diseases can be discoloration, bending, wilting, darkness, chlorosis, redness and various damage to the leaf surface of many plants and roots. For example, traces of enveloping roots that appear during root rot, as is the case with causes called “white rot,” signal a harmful fungus that becomes the reason for the onset of plant disease. - Symptoms of fungal infections manifest themselves differently, based on the characteristics of the pathological process. In many cases, a newly planted seedling is affected at the very neck. It is important to note that the lesions initially appear as small brown spots. As the lesion develops, the affected area noticeably increases in size. Subsequently, the affected tissue dries out and is easily separated, but the base of the plant stem remains, which continues to grow and form flowers and fruits.
