Amino oligosaccharins, also known as chitosan oligosaccharides(COS) for agriculture. It is an oligosaccharide product obtained by degrading chitosan through special bio-enzyme technology. Its degree of polymerization is between 2 and 20. And there are two types: solid and liquid.

Tea trees will encounter common tea red spot and anthracnose during their growth. If we want tea trees to get less sick, we need to start from below two aspects:

  1. Before the disease occurs: use 750-1000 times of amino oligosaccharin water agent to evenly spray the stems and leaves of tea trees, spray once every 7 days, and spray 3 times in a row. That can effectively prevent tea red spot and anthracnose of tea trees .
  2. Early stage of the disease: we should use related products in combination with amino oligosaccharins, such as:
    Amino oligosaccharin liquid 1000 times + 25% propiconazole EC 1000-2000 times.
    Amino oligosaccharin aqueous solution 1000 times + 40% pheniconazole microemulsion 2000-3000 times in combination.

Please note that: Related fungicide products should be used alternately to avoid resistance.

Anticipated Effects of amino oligosaccharins:

  1. Improve the stress resistance of tea trees;
  2. Promote the growth of tea trees;
  3. Increase the number of new buds of tea trees, and increase production.

Amino oligosaccharins synergistic application with related chemical fungicides has below effects:

  1. Improve the efficacy and reduce the use content of chemical pesticides,
  2. Reduce and delay the occurrence of diseases,
  3. The effect of preventing and controlling tea spot disease can reach 60-90%, and anthracnose can reach 75-80%.

Studies have shown that the effect of conventional planting management in the budding stage of tea is compared with the use of 1000 times solution of amino oligosaccharin water agent. The results show that the treatment of tea trees with amino oligosaccharin can effectively promote the growth of tea trees, and the control effect of preventing tea tree anthracnose is 80%.
