Symptoms Brown-branch tendon rot occurs mainly on the surface of the fruit, with localized browning, irregularities, and firm flesh. Vascular bundles in the skin become brown and necrotic. Usually the lower inflorescences have more fruits than the upper inflorescences. Albino tendon rot occurs mostly in the tissues of the pericarp, and the diseased part has a waxy luster and poor coloration.
The occurrence of tendon rot disease has a close relationship with soil moisture. Soils with high irrigation and high groundwater levels are more severe. Large amount of fertilizer, especially when the ammonia nitrogen fertilizer is used excessively, affects the absorption of phosphorus and potassium fertilizers, and the incidence is heavier. The use of unfamiliar farmyard manure, dense planting, and forced topping are all very prone to disease. At the same time, the disease has a great relationship with the species.
The control methods selected varieties that are not susceptible to browning tendon rot. In the cultivation, it is necessary to avoid the phenomenon of insufficient sunlight, multiple fertilizers, and insufficient supply of oxygen in the soil. Increased light, slightly sparsely planted, moderate amount of nitrogen fertilizer, and no phosphorus and potassium fertilizers. The greenhouse in the low-lying ground should pay attention to drainage.
