Agricultural chitosan plant antifreeze formula

Agricultural chitosan plant antifreeze formula

 Yuda chitosan oligosaccharide is a functional sugar extracted from shrimp and crab shells/fungi/mushrooms. It is currently widely used in pesticides and fertilizers to resist nematodes, induce stress resistance, and increase per-acre yield.

 Low temperature stress can stimulate the response of cold receptor cells in plants, causing chronic or long-term effects on cell metabolism and molecular functions, reducing photosynthesis, and even directly leading to plant death. As a biostimulant, chitosan oligosaccharide can promote plant growth after low-dose spraying, while regulating the content of soluble sugar and proline, and increasing the expression of genes related to antioxidant enzyme activity to reduce the content of active oxygen, thus increasing the activity of antioxidant enzymes and The activity of enzymes related to nitrogen metabolism increases the ability to cope with abiotic stress.

 Anti-low temperature formula: calcium nitrate tetrahydrate, potassium nitrate, ammonium nitrate, potassium dihydrogen phosphate, magnesium sulfate heptahydrate, potassium iodide, zinc sulfate, boric acid, manganese sulfate, sodium molybdate, copper sulfate, and cobalt chloride. The concentration of added chitosan oligosaccharide is 100ppm-150ppm. It is recommended to spray it 3 times before low temperature, with an interval of 3-4 days. It can also be used for a long time during low temperature, with an interval of 10 days. It can significantly improve the damage to crops caused by low temperature or late spring cold.
