I. Diseases and control of millet pepper

The common diseases of millet pepper are quenching, root rot, bacterial wilt, virus, blight, powdery mildew, anthrax and so on.

The quenching disease of millet pepper is mainly infected at the young seedling cotyledon stage or before the true leaves are unfolded. After the seedlings are unearthed, waterlogged spots appear near the ground at the base of the stem, gradually yellowing, constricting and sunken, and the leaves are quenched before withering. It is easy to fall off from the disease spot by hand, and the white cotton hairy mildew layer can be seen in the wet part. The control method is to use "Miaoyingchun" 3000 times (5ml/15 kg) + 72.2% aldicarb hydrochloride 1500 times (10ml/15 kg) + 70% imidacloprid 5000 times (3 g / 15 kg)), root irrigation or spray control.

The symptom of root rot disease is that the base of the stem and the root cortex of the diseased plant turn brown to dark brown and wet rot, and the root cortex of the diseased plant falls off or peels off to reveal dark xylem. Generally, the plant will be stunted and short, and sodium dichloroisocyanurate can be used in the early stage of the disease. Chlorothalonil, thiram, or difenoconazole and other agents for prevention and treatment.

The symptom of millet pepper bacterial wilt is that the leaves turn yellow gradually from bottom to top, fall off in large numbers, or the basal cortex of the stem at the contact with the ground is flooded, and the aboveground stems and leaves wither rapidly. The control method is to use "Miaoyingchun" 3000 times (5ml/15 kg) + 72.2% agricultural streptomycin 3000 times (5ml/15 kg), and the seedlings are irrigated for 7 days.

The common symptoms of virus disease are foliage shrinkage or brown necrosis, systemic necrotic stripes, dark green and light green spots on the fruit. Generally, 20% morpholine guanidine, copper acetate 750x (20g / 15kg) + 5000 imidacloprid 5000 times (3g / 15kg) + Lei Li 2000 (1000 times) or Jinshan 600x were sprayed.

In case of epidemic disease, drainage should be done in time. 58% metalaxyl, 600 times zinc (25 g / 15 kg), 25% metalaxyl, 600 times urea cyanide (25 g / 15 kg), 65% clasp and other drugs can be used for treatment. The disease occurs in seedling stage, mature stage and fruiting stage, and brown constriction usually occurs at the base of the stem.

Powdery mildew mainly occurs in leaves. At the initial stage, round white spots grow on the front or back, and gradually expand into large powder spots. In the later stage, the whole leaf is covered with powdery mildew, which finally leads to a large number of leaves falling off. Chlorothalonil, hexazolol or pyrazole were generally used for control.

The consequence of anthracnose is a large number of fallen leaves and rotten fruits, which can be prevented and treated with world blue 30% difenoconazole (5 g / 15 kg), 45% imidamide 2000 times (7.5ml/15 kg) and Mei Bang 50% nail suspension 600 times (25ml/15 kg).

Compared with drug treatment, it is more important to carry out early prevention. When selecting millet pepper varieties, we should choose varieties with strong disease resistance and disinfect the seeds as far as possible before sowing.
