1. Anthracnose in pepper is mainly characterized by brownish water-stained round or irregular shaped lesions on the fruit surface. The diameter is about 1 cm. Most of them are subsidence. The sick and healthy junctions are obvious, and the spots are black or orange-red. This kind of lesion is easy to shrink and break when it is dry, and hangs like a tiger skin, so it is also called "tiger disease". When wet, the surface of the fruit overflowed with red sticky material, and the diseased fruit rotted off. Often hanging on the fruit branch, high temperature and high humidity are easy to attack, spread quickly, often cause greater losses within a week. Control methods: After the detection of diseased plants, select 80% of anthraquinone omeprazole WP 800 times or 75% chlorothalonil WP 500 to 600 times or 70% Mancozeb WP 400 to 500 times. Or 70% thiophanate-methyl WP wet spray 600 to 800 times, 7 to 10 days spray 1, even spray 3 times. Second, hot pepper rot Mainly affect the fruit, the disease mostly occurs on the green fruit, the skin is dark green spots, then it turns brown and soft rot, with bad odor, the internal pulp rot, the fruit is deformed, as if the bag filled with muddy water, and some Called "a bucket of water." After the fruit was dehydrated, it shrank, leaving only the grayish-white peels hanging on the vines. Control methods: Spray 72% of agricultural streptomycin wettable powder 4000 times, 50% of copper succinate wettable powder 500 times, 77% of wettable powder 500 times, etc. in time after rain. Spray 7 times a day, even spray 3 to 4 times. Third, pepper virus disease The performance of the field was mosaic, yellowing, necrosis and deformity. The general appearance is mosaic, and when severe, several symptoms occur at the same time, causing a large number of fallen leaves, falling flowers, falling fruit and necrosis at the growing point. Control methods: Use virus K, virus A, virus spirit or virus net 400 to 500 times the liquid in the early stages of disease use, 7 days spray 1, even spray 3 times. Spraying with 0.1% potassium permanganate or 20 mg/kg naphthalene acetic acid or 1% superphosphate solution also has certain control effect on mosaic virus. Fourth, the pepper blight When the black long spots are clearly formed, the lesions rapidly spread around the stems and are 3 to 5 cm long or longer. The lesions and junctions are distinct and the lesions are slightly sunken or constricted. A large round of water-soaked lesions are formed on the tip of the leaf or on the leaf margin, and the entire leaf is soft rotted and withered. The fruit began to develop from the pedicle, showing a dark green immersion, quickly turning brown and soft rot. The late loss of water shrinks and shrinks without falling off. Wet grayish-white moldy material can be seen in the wet. Control methods: After discovering the central disease strain, 50% methicone wettable powder 500 to 600 times liquid, 60% DTM WP 500 times, 77% WP 500 times, 75% 100% can be used. Bacteria clear wettable powder 800 times liquid spray control, 7 to 10 days spray 1, even spray 2 to 3 times, severe spray every 5 days 1, even spray 3 to 4 times.
With PSA principles, ETR medical PSA Oxygen Generator can produce 93%±3% purity oxygen gas directly from compressed air. Compared with
traditional Bulk liquid oxygen and cylinders oxygen, ETR on-site PSA oxygen
generator can reduce cost down to 50 percentages. They can produce oxygen by
your will, overcoming the limits of distance, location and transportation.
Compressed air is purified through the air dryer and
filters to a certain level for main generator to work with. Air buffer is
incorporated for smooth supply of compressed air thus to reduce fluctuation of
compressed air source. The generator produces oxygen with PSA (pressure swing
adsorption) technology, which is a time proven oxygen generation method. Oxygen
of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply
of product gas. Oxygen in buffer tank is maintained at 4bar pressure.
