Amino oligosaccharins is a bio-fungicide extracted from the microbial fermentation, oligochitosan itself is rich in C, N, and can be degraded by microorganisms use as a plant growth nutrients.
Characteristics mechanism
Amino Oligosaccharins (agricultural grade Amino chitosan) able to inhibit the growth of some bacteria, fungi spore germination, mycelial morphogenesis induced mutation, track biochemical changes and so on. Can stimulate the genes in plants to produce chitinase, has antiviral effects, glucanase and PR protein, and cell activation, help restore damaged facilities and promote root seedlings, improve crop resistance, and promote plant growth and development. Amino Oligosaccharins solution with anti-virus, kill bacteria, antifungal effect. It can be widely used to control fruit, vegetables, underground rhizomes, tobacco, medicines and corn and cotton crops, fungi, bacteria, viruses cause mosaic disease, lobular disease, scab, anthracnose, downy mildew, blight, gummy stem blight yellow dwarf virus, blast, bacterial wilt, rot and other diseases.
Functional role
As a biological pesticide, chitosan oligosaccharide has numerous disease preventive and disease mechanisms, as well as an active signaling molecules rapidly stimulate plant defense response, induce plant to produce phenolic compounds, lignin, phytoalexins, duration and other diseases related to protein substances associated with disease and improve defense enzymes. Typically believed that amino Oligosaccharins antibacterial mechanism: Under acidic conditions, bacterial cell wall contains amino Oligosaccharins molecular NH silicate, phosphate, etc. dissociated anion binding, thus preventing bacteria multiply; then, the low molecular weight amino acids Oligosaccharins further through the cell wall, into the microbial cells, the genetic factors prevented the process of transcription from DNA to RNA, causing microbes completely unable to reproduce. The amino Oligosaccharins used in the manufacture of bio-pesticides is the future direction of development, it is easy to decompose in nature, it will not pollute the environment, both power and bio-fertilizer dual regulatory function, and can be induced immune activation in plants improve plant antiviral capabilities. Currently amino Oligosaccharins, after extensive field trials on watermelon wilt, Phytophthora infestans, tobacco virus disease, powdery mildew, blight lettuce, peppers, etc. is a good control agent.
Second, the plant functional regulator amino Oligosaccharins act as a plant regulator, with activation of plant cells, promoting plant growth regulating, activate plant defense reactions, starting antiviral gene expression and so on. Japan has made amino Oligosaccharins as a plant growth regulator, used to improve the yield of some crops. An research on a role in promoting growth of cucumber by amino Oligosaccharins, results showed that amino Oligosaccharins treated cucumber plants not only improved resistance to downy mildew, but also for fruit harvest in advance 3 ~ 5d, yield improved considerably.
Third, seed coatings amino Oligosaccharins as a plant growth regulator and anti-bacterial agents, can induce the plant to produce proteins and phytoalexin PR use as the basic immune.
Fourth, crop resilience agent amino Oligosaccharins (Oligochitosan) induced crop not only in disease resistance (biotic stress) terms, but also in terms of resistance to abiotic stresses. Administration of amino acids Oligosaccharins have a good effect on anti-cold, high temperature, drought resistant, saline-alkali, anti fertilizer damage, anti-nutritional imbalance, etc. . This is due to amino Oligosaccharins itself has a positive effect in many areas, induce a variety of resistance, reduce or correct stress in plant cells from harmful effects and promote crop to grow strong, sturdy plants naturally. Many agronomists found in practice, in the case of seedlings suffer cold damage or wilting, timely administration of amino Oligosaccharins quickly restored the plants grow; when crops underlying causes of aging, the application of amino Oligosaccharins precipitating energetic new roots., when crops suffered damage resulting in pesticide or dieback, application of amino Oligosaccharins to help detoxify and draw new branches.
Field application
1. Prevention of melons, eggplant fruit viral disease, Botrytis cinerea, anthrax and other diseases..
Spraying about once every 10 days from seedling stage, by 1000 times with a 2% amino Oligosaccharins, continuous spray 2-3 times, can prevent the occurrence of these diseases.
2.Control of tobacco mosaic virus, blackleg and other diseases..
Spraying around once every 10 days from seedling stage, by 1,000 times dilution with a 2% amino Oligosaccharins, continuous spray 2-3 times, can effectively control viral diseases, blackleg and other diseases from occurring.
Types of chitosan :
There are few grades available in the market, i am sharing base on personnal understanding … some traders / growers add humic acid or seaweed into the chitosan to make it looks kaw-kaw (thicker).
Control target :
Viruses cause mosaic disease, lobular disease, scab, anthracnose, downy mildew, blight, gummy stem, yellow dwarf virus, , bacterial wilt, rot and other diseases.
Dosage:
Dilution in 800-1000 fold foliar spray as preventative measure and soil drench if early disease detection
Standard packing available ….
