Grape Cob Brown Blight Control Measures
1. Diseases: Grape brown leaf blight is a new disease on the grapes. The grapevines suffering from severe damage have a large amount of shedding of the small spike axis and small young fruit, which affects the yield and quality. In the early stage of the onset of the spikelet, a small brownish brown spot appears on the rachis branch of the branch, soon becomes brownish and necrotic, and dryness turns dark brown. After the young fruit shrinks, the cob is left, and then the dry ear is dried. The shaft is blown or touched and it falls off from the branches. After the young fruit is killed, there are two symptoms: (1) Initially, small, brown, irregular patches of flaky fruit appear on small fruit pieces, which quickly spread to the whole grains, becoming dark brown and shrinking and falling off; The dark brown and black round spots appeared on the young fruit. The spots did not sag and the young fruit did not fall off. As the fruit size increased, the diseased spot appeared as shedding, which only affected the appearance and did not affect the fruit growth and development.
2, the incidence of law. The incidence of heavy rain and low temperature during the flowering period is light, and vice versa. The occurrence of the disease is concentrated around the flowering period, only harm the axis of the spikelets and young fruit, does not harm the branches and leaves.
3, prevention measures. 1 Construct water conservancy, reduce water level, remove weeds, and improve ventilation and light transmission conditions. 2 One-week flowering period and initial flowering period, combining control of black pox and gray mold, spraying Bordeaux mixture, carbendazim or thiophanate-methyl. 3 0.5 to 1 gram (active ingredient) of paclobutrazol per plant roots for 18 days before flowering can significantly increase the disease resistance of branching cobs.
An oxygen concentrator is a type of medical device used for delivering
oxygen to individuals with breathing-related disorders. Individuals
whose oxygen concentration in their blood is lower than normal often
require an oxygen concentrator to replace that oxygen.
Generally,
you can`t buy an oxygen concentrator over the counter. A doctor must
prescribe it after they`ve completed a thorough medical evaluation. The
doctors will also typically show the patients how to effectively use
these concentrators while traveling and in their home.
Oxygen
concentrators filter surrounding air, compressing it to the required
density and then delivering purified medical grade oxygen into a
pulse-dose delivery system or continuous stream system to the patient.
It`s also equipped with special filters and sieve beds which help remove Nitrogen from the air to ensure delivery of completely purified oxygen to the patient. These devices also come with an electronic user interface so you can adjust the levels of oxygen concentration and delivery settings. You then inhale the oxygen through the nasal cannula or special mask.
