The stem support is used with grafted and topped tomato plants and prevents tearing of the plant thus reducing the risk of Fusarium and Botrytis infections. The stem support is easy to use: it should be placed before the crops are lowered for the first time. Then, it is left in position for at least the next two times the crops are lowered. This helps prevent torn stems and reduces the risk of Fusarium and Botrytis infections. The stem holders are especially important during the first times growers lower the tomato plants. The stem support is available in plastic and biodegradable material.
