The pathogenicity of the pathogen occurs when the mycelium adheres to the host or the sick and the body overwinters. In the following year, the conidia are produced by airflow and rain. Warm and rainy summer is more severe.
Diagnosis of the disease mainly damages onion leaves, pedicels, but also harm the bulb. Lesions usually start at the tip of the leaf or in the middle of the pedicel and then spread to the lower part. The initial lesion was a slightly whiteish spot, followed by an enlarged oval or spindle-shaped lesion. Spot size and color vary depending on the host species. Onions and leeks were purple-brown in color and larger; garlic was yellowish-brown in color and smaller in size. When the humidity is high, the disease minister is brown to dark brown powdery mildew (conidial stems and conidia), often arranged in a concentric ring pattern, and the diseased part is easily broken.
The control method used disease-free seeds and was washed with water after 40% formalin 300-fold immersion for 3 hours. After cleaning, remove the diseased body and turn the soil deeply; select well-drained and well-fertilized plant; apply enough basic fertilizer to increase phosphate fertilizer; store the cellar to maintain low temperature and low humidity (0°C and relative humidity 65%), and pay attention to ventilation to prevent storage period. Bulbs continue to develop.
At the beginning of the disease, the chemical can be sprayed with 75% chlorothalonil wettable powder, 58% metalaxyl MnZn WP 500 times, once every 7 to 10 days, and even sprayed three times.
Sunson Desizing Enzyme is designed for for textile desizing process. Desizing enzyme is a compound composed by amylase produced by microbial fermentation and other effective substances. It can be used in textile industry to decompose the starch in fabric pulp into short chain dextrin and oligosaccharide, so that the starch can be easily removed in the latter process. Currently, there are two kinds of amylase used for desizing: high temperature resistant Alpha Amylase and medium temperature amylase.
Desizing enzyme's characteristics: high efficiency, suitable for high temperature, fast desizing speed, desizing rate can reach 90% to 95%. The fabric is soft, plump, smooth, bright staining after desizing. Desizing and fixation can treated in the same bath treatment. It can shorten the process flow and improve labor productivity.
Conzyme DD365L is liquid alpha amylase preparation. It is specially developed for textile desizing process, which can completely remove the starch based sizes in wide temperature condition.
Conzyme LTAA3L is liquid and low temperature alpha amylase preparation. It is specially developed for textile desizing process, which can completely remove the starch based sizes in wide temperature condition.
Benefits:
Complete removal of all types of starch-based sizes
Excellent efficiency in low temperature, energy saving
Environmentally friendly solution
This product should be stored in a cool and dry place in sealed container, avoiding insolation, high temperature and damp. The product has been formulated for optimal stability. Extended storage or adverse conditions such as higher temperature or higher humidity may lead to a higher dosage requirement.
Enzyme preparations belong to protein, which may induce sensitization and cause anaphylaxis in sensitized individuals. Long-term exposure may cause minor irritation for skin, eyes or nasal mucosa, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
