Control measures against spot blight of celery

According to the survey, spot blight has occurred in some parts of the celery crops, and there are lesions on the celery leaves, petioles, and stems, which are serious. This is because the weather gradually cools after the fall and the air humidity is relatively high at night, which is suitable for disease development. The occurrence of the disease has a great impact on the yield and quality, especially after the late autumn cultivation, it should be prevented as soon as possible.
There are two symptoms of pathological diagnosis, one is the old leaf first onset, and then spread to the new leaf. The lesions on the leaves are mostly scattered, ranging in size from 3 to 10 mm in diameter, starting with light brown oily spots. After the gradual expansion, the central brown necrosis, the outer edge is mostly dark red brown, a small amount of small black spots scattered in the middle. The other is that the center of the lesion is yellow or gray in the middle of the lesion, and the edge gathers many small black particles. The lesion often has a yellow halo outside the lesion, and the lesion diameter varies. The petiole or stem was infected, the lesion was brown, the oval was slightly sunken, and the center had scattered black dots. The disease can be transmitted through seeds and sicknesses. It is prone to occur in cool and hot conditions. The temperature is 20°C~25°C and the humidity is heavy. In addition, even when it is cloudy or rainy during the day, the disease may be heavy when there is fog or dew at night and the temperature is too low and the resistance of the plants is weak.
Control methods
1, seed disinfection. Soaking with warm water at 49°C for 30 minutes, stirring while immersing and then moving into cool water, cooling, drying after sowing.
2. Strengthen field management. Apply enough base fertilizer and top-dressing to increase plant resistance to disease.
3, after the autumn delay greenhouse cultivation, pay attention to cooling and humidity. Keep 15°C~20°C during the day and 10°C~15°C during the night, reduce the temperature difference between day and night, reduce condensation, and avoid flooding.
4, pharmaceutical control. Early prevention before the onset of disease, open ground can be used 75% of Dakenin WP 600 times or 64% anti-tussive WP 500 times or 50% carbendazim WP 500 times or 50% SRK 500 times Spray, use alternately, control once every 7-10 days, prevent 2~3 times. The cultivation of greenhouses can use chlorothalonil or quick-release aerosol smoke sheds.

Sunson Denim Finishing Enzyme is designed for denim finishing processing. Cellulase is regarded as a "biological pumice", which makes the indigo dye separated from denim on the washing process, and a few doses of enzyme can replace several kilograms of pumice. The less use of pumice, the smaller  damage to the clothing and the smaller loss of the machine and the less sand dust in the washing environment. "Biological pumice" provides a possibility for increasing the effect of the finishing process. For example, it is possible to decolorization jeans without damaging the fabric. And the washing machine can contain less pumice and more clothing, and can also improve the production efficiency greatly.

Coenzyme N-3000 is high concentrated and neutral cellulase preparation, which is designed specially for denim abrasion process. It is only recommended for formulations that are used in bio-washing of denim garments and acts on denim garments to impart high abrasion and fading effect, which can also be used for the processing of the cotton, hemp, viscose, yarn and Lyocell.

Coenzyme NL Ultra is high concentrated and liquid neutral cellulase preparation. It is specially developed for fabric and garment biopolishing under neutral condition; it can combine with hydrogen peroxide removal in the same dye bath, and is exclusively designed for formulator.

Coenzyme NL Ultra II is new developed and high concentrated neutral cellulase preparation. It is designed for fabric and garment biopolishing under neutral condition, and specially developed for denim abrasion with high contrast and low back staining; it can combine with hydrogen peroxide removal in the same dye bath, and is exclusively designed for formulator.

Benefits:

Excellent bio-polishing effect

Clean and even fabric surface
Softer handfeel
Brighter colors
Environmental-friendly & bio-degradation
