How to prevent wheat sheath blight

November 17 06:02:55, 2019

Wheat sheath blight can be damaged during the whole growing period of wheat. Wheat just emerged can be infected by bacteria, initially producing small yellow spots on leaf sheaths, followed by the development of yellow-brown shuttle-like lesions. After the jointing of wheat, the disease department gradually expanded, often forming a moiré pattern, and also expanded inwards to harm the stem, resulting in a bad stalk of the flower stalk, severe diseased plant withered, and the formation of a dry plant with white spikes.
To prevent the occurrence of wheat sheath blight, it is necessary to plant sowing seeds in an appropriate period and plant them in a close-packed manner to avoid excessive density, reasonable fertilization, and timely weed control. Focus on seed dressings and seed dressings, and use 2.5% of Shiloh's suspension seed coating agent for 10-20 ml of water to add 100-200 ml of water; use 5% Jinggangmycin for 150-200 ml or 12.5 ml of water per acre in the jointing stage of wheat. % Ke Guoli WP 20-30 g or 15% Triadimefon WP 50-100 g, 70% thiophanate-methyl wettable powder 50-75 g or 50% carbendazim wettable powder 50 - 100 grams of water spray 60-75 kg.

Goji Polysaccharides is a rare plant polysaccharides containing protein, which have side chains of polysaccharide composed by six carbon sugars (rhamnose, arabinose, xylose, mannose, galactose, glucose) and main chains of protein composed by 18 kinds of amino acids. The glycoproteins with biological activity is a high-strength immune enhancer.

Wolfberry products with stable quality are all natural, safe, sanitary and fast absorption.Lycium barbarum polysaccharide extraction and purification is divided into two steps. First, the extraction of Chinese wolfberry crude polysaccharides, the second is purified Lycium barbarum polysaccharide. Crude polysaccharides extraction process is as follows: Weigh dried crushed medlar, petroleum ether: acetone (1: 1) reflux degreasing, the solvent was filtered off, the residue was air-dried 80% ethanol off monosaccharide and oligosaccharides. 
The polysaccharide is extracted by water after dissolving the residues such as oligosaccharides in water at 90-100 DEG C, the extract is concentrated under reduced pressure, the polysaccharides are precipitated by ethanol, the precipitates are washed with anhydrous ethanol and acetone, and the lycium polysaccharides are dried under vacuum. The crude polysaccharide is purified by passing the Lycium barbarum polysaccharide through a column of DEAE cellulose with different concentrations of NaCl as an eluent, concentrating the eluates with different salt concentrations respectively under reduced pressure, desalting them by dialysis, and then lyophilizing them differently Grape Lycium glycoprotein.

Goji Polysaccharides 

Modern medical research suggests that wolfberry polysaccharides can improve human immunity and have functions as anti-cancer, cancer treatment, hematopoiesis, liver protection and hypotensive, free radicals removal , anti-fatigue, anti-radiation, and cell activity improvement; Goji polysaccharides can control cells division& differentiation, and regulate cell growth & aging, which is widely used in the pharmaceutical, health food and other fields.
