Beet bacterial spot blight

Symptoms are also called bacterial scabs. The main damage is leaf, petiole and moss stems. The leaves were infected with yellowish-brown water-stained spots, which gradually expanded into round or irregular shaped lesions with a pale yellow-brown mid-brown and dark brown or dark brown edges. The shape of the lesion varies depending on where it is located. When the lesions spread to the veins, the veins turned black, and the lesions continued to spread along the veins, showing stripes. Lesions are wavy at the margins. The petiole was infected with black-brown streaks, and when the humidity was high, it was watery and rotted. The diseased stem of the moss produces black-brown strips with severe stem curvature.

The pathogen Pseudomonas syringae pv. aptata (Brown et al.) Young et al. called Pseudomonas syringae beetogenic disease. Synonyms P.aptata (Brown et Jamieson) Stevens. Rod-shaped, size 1.2-3.20.6-1.3 (μm), no spores, no capsule, 1-3 flagella. Gram-negative staining. Arousal. On the gravy agar plane colonies white, round, smooth surface, shiny, neat edges. The optimal growth temperature is 27-28°C, the highest is 34-35°C, the lowest is -1°C, and the lethal temperature is 47.5-48°C.

Transmission routes and pathogenic conditions The pathogens attach to the bulbs or the dead leaves and they pass through the wind and rain. Invade the leaf tissue from the wounds of sugar beet leaves.

In the northeastern part of northeastern China, the disease began in mid-June, and in July and August, the high-temperature and rainy seasons spread rapidly. After the end of August, the expansion stopped with decreasing temperatures. The onset of the field is closely related to temperature and humidity. Generally, the disease spreads quickly when the climate is dry and cloudy or before rain and beet irrigated. High temperature and high humidity are important conditions for disease. When the outside temperature and humidity are suitable, the diseased plants will appear in large numbers and spread rapidly, otherwise diseased plants will rarely be found.

The prevention and treatment methods currently have no ideal prevention and treatment methods for the disease. (1) When the bacterial seed spot is found in the seed collection site due to the beet seed, the diseased flowering moss is immediately removed to prevent infection. (2) Seed Disinfection After sowing with 0.8% of 70% aldehyde soaked for 5 minutes, remove the boring seeds for 2 hours to allow them to continue their fumigation, and then spread the seeds to be allowed to dry before sowing. (3) Remove the sick body from the field, and turn the diseased body deep into the soil in time in autumn. (4) Applying 10 kg of calcium phosphate per 667 m2 during the sowing of additional phosphate fertilizer. After planting, the amount of nitrogen fertilizer was pursued to accelerate the growth and development of leaf organs. Increase disease resistance. (5) If necessary, spray 72% of agricultural streptomycin sulfate 3000-4000 times or 12% green milk copper emulsion 600 times, 47% Garnett's wettable powder 700-800 times.

Huller & Others

 

The huller machine is used to remove shell or husks from grain, seed, rice, coffee bean, which is necessary steps for further processing.

 

We have varies models of huller machine.

The Grain Huller is our popular type huller machine, it can be used for millet, maize, wheat, barley, oats, beans etc.

It can process different products by adjusting sand wheel and sieve size.

Its working principle is that, by friction of sand wheel with sieves, to remove husks from grain, and the husks and grain will be separately totally by air flow.

There is control handle to control narrow of hulling chamber , to adjust hulling results easily.

 

 

The Coffee Pulper is used for fresh coffee beans. It is used to remove fresh shell from coffee beans. It is manual type, capacity 40-60kg/h.

 

The Rice Huller With Polisher machine is specially used for rice, it can remove husks from paddy, at the same time , polish rice to be whitener.

 

We also have Vegetable Seed Cleaner and Seed Grading Machine.

The Vegetable Seed Cleaner is often used for processing vegetable seed or grass seed, it has compact structure with air aspiration system and vibration system, suitable to remove dust, light impurities, large and small impurities from good grain or seed.

 

The Seed Grading Machine is for sizing and grading of different kind of grain and seed. It can be used for varies kind of seed, grain, beans by changing different sieves.
