The editor introduces the content about ornamental chili peppers to you, including the control of tea yellow mites on ornamental chili peppers. Let's learn about it together.
The tea yellow mite is one of the more harmful mites affecting vegetables, and its damage to vegetables has been increasing in recent years. It has a diverse diet and a wide range of host plants, with over 70 known hosts. It mainly damages vegetables such as cucumbers, eggplants, chili peppers, potatoes, tomatoes, melons, legumes, celery, Malabar spinach, radishes, etc.
Ornamental chili peppers are also affected by tea yellow mites. Here is an introduction to the control methods for tea yellow mites on ornamental chili peppers:
I. Characteristics of Damage
After being infested, the underside of the leaves of ornamental chili peppers appears greasy, gradually turning yellowish-brown or grayish-brown, the leaf edges curl downward, the young stems turn yellowish-brown, severely affected plants become stunted, bushy, with dropped flowers and fruits, forming bare tips, the fruit stems and tips turn yellowish-brown, lose their luster, and the fruit growth stops and hardens. As a result, ornamental chili peppers lose their original value both in appearance and for consumption.
II. Morphological Characteristics
The female mites are about 0.21 mm long, elliptical, light yellow to orange, semi-transparent, with 5 pairs of shorter legs. The male adult mites are similar to hexagons, with a conical end, smaller than females, about 0.18 mm long, light yellow to orange, semi-transparent, with longer and stouter legs.
III. Habits of Life
It takes 7 to 10 days to complete a generation at temperatures between 20°C to 30°C. In greenhouses under suitable conditions, it can occur throughout the year. Tea yellow mites mainly reproduce sexually, but can also reproduce thelytokously, although unfertilized eggs have a low hatching rate and are all male. Eggs are mostly scattered on the back of young leaves and in the concave parts of fruits. Both adult and larval mites are attracted to young tissues, especially the back of young leaves. The optimal temperature for the growth and reproduction of tea yellow mites is between 16°C to 23°C, with a relative humidity of 80% to 90%. High temperatures inhibit their reproduction, and heavy rain can reduce the population.
III. Control Measures
1. Regularly inspect the plants, and if tea yellow mites are found during the early flowering stage of chili peppers, spray pesticides promptly. Continue to spray every 10 to 14 days, for a total of 3 times.
2. The focus of spraying is on the upper leaves, especially the back of young leaves, young stems, flowers, and young fruits. Pesticides that can be used include 57% Kelimate emulsion 800 times dilution, 48% Lestos emulsion 1500 times dilution, etc.
3. If tea yellow mites are found in individual pots or containers, isolate them promptly to prevent infection.
4. Any branches, leaves, flowers, and fruits contaminated with mite eggs should be cut off and burned to prevent further hatching of eggs.
