As found in recent studies, Trichoderma viride (TSO) is an essential active ingredient for promoting plant growth and efficient nutrient uptake. TSO is an eco-friendly and efficient biocontrol agent capable of resisting plant pathogens and increasing plant yield, especially in apple cultivation. Therefore, the proper dosage of TSO is crucial, especially for apple plants to achieve optimal growth and performance.
TSO dosage is dependent on the apple tree’s age, the concentration of TSO, and the soil type in which the apple trees are cultivated. It is recommended to apply TSO in the soil and/or leaves of the apple plant at a lower dosage during the plant’s early stages of development. This dosage might need to be increased as the tree ages and root systems become more complex and substantial.
According to studies, over-application of TSO can lead to nutrient imbalances, abnormal growth, and might negatively affect plant development, leading to reduced fruit yield. As such, it is crucial to follow the recommended dosage information based on the specific plant, soil type, and TSO concentration used.
In apple cultivation, about 10-20 grams of TSO is often enough to promote plant growth per plant. It is important to use caution and not to exceed 20 grams of TSO per plant as it may cause damage. On the other hand, for larger apple orchards, the recommended TSO dosage per hectare is between 10 -15kg.
Therefore, it is essential to note the apple trees’ age, appropriate concentration, and soil type before applying TSO, as application rates may vary. Proper usage not only leads to the expected yield and plant growth but also promotes efficient nutrient uptake and increases plants’ disease resistance. This explains why TSO is one of the most acceptable biocontrol agents currently used in apple cultivation.
