What are the common diseases of the pepino melon? A detailed explanation of prevention and control methods
The pepino melon (Solanum muricatum) is a delicious fruit with extremely high nutritional value, rich in high protein, multiple vitamins and large amounts of essential trace elements for the human body, and it is relatively well liked. But any plant is inevitably troubled by diseases, and the pepino melon is no exception, so what diseases does the pepino melon have? And how should they be prevented and controlled? Below, the editor brings you the common diseases of the pepino melon and their prevention and control methods.
Phytophthora fruit rot
Phytophthora fruit rot occurs in the high-temperature, rainy seasons of July and August, and is more severe in heavy clay soil. When the disease strikes, light brown spots appear on the fruit along with white mold patches; as the disease progresses, the spot color gradually darkens, and the flesh also turns brown. When humidity is too high, the fruit stops growing and developing. It falls off easily and also gradually infects the leaves; diseased leaves develop large chlorotic spots and gradually rot.
Prevention and control methods: when planting, choose fertile areas with good drainage; after planting, cover the ground with plastic film to prevent rainwater from splashing up pathogens. Frequently apply organic phosphorus and potassium fertilizers to increase disease resistance, prune excess branches and twigs in time, and for greenhouse cultivation pay attention to ventilation and light penetration. When disease is found, promptly remove diseased fruits and leaves; the usual disposal method is deep burial or direct burning.
Sooty mold
Sooty mold develops relatively quickly. The pathogen of sooty mold is a fungus, which mostly overwinters dormant in soil and plant debris, then awakens in early spring the following year to produce spores that spread rapidly through air, wind and rain, and insects. It has already occurred in shaded, humid greenhouses, and is prone to occur during the plum rain season.
Prevention and control methods: pay attention to ventilation and air circulation; in high temperature and high humidity, pay attention to lowering temperature and humidity; watering should be appropriate.
Black spot
Black spot mainly harms the leaves. In the early stage of the disease, black spots appear on the leaves; as the disease worsens, the leaf spots gradually expand, eventually causing the leaves to dry up or necrose.
Prevention and control methods: because the day-night temperature difference in spring and summer is too large, which favors the occurrence and spread of black spot, attention should be paid to regulating the temperature difference to prevent the occurrence and spread of this disease.
