AG100 is a microbially based product produced by Cleveland Biotech Limited UK. It consists of a mixture of components including bacteria. The product is supplied in a cellulose based semi permeable sachet ready for incubation.
Work performed during the summer at Cockle Park Experimental Station, Northumberland England and Growers trials in Australia found that application of AG100 to hydroponically grown crops produced positive results for growth rate and disease control. These experiments showed that plants treated with AG100 produced higher harvestable weights and a reduction in certain diseases such as Botrytis cinerea when compared to untreated plants. A series of experiments were undertaken in order to further investigate the benefits of AG100 in a more scientifically exacting environment. These experiments were performed at Cockle Park Experimental Station by the University of Newcastle upon Tyne as part of a postgraduate research programme. This report summarises the results of these experiments.
There were two main areas of investigation -
- To investigate the effects of application of AG100 on lettuce grown in a commercial hydroponics system. The aim was to determine if the product produced any positive effects on growth or levels of Botrytis.
- The second stage was to determine which if any of the main components were causing the beneficial effects. Four different forms of AG100 were prepared, each one having a major component removed.
The experiments performed have shown:-
- Applications of AG100 can increase leaf and total dry weights of harvestable crop.
- Treated plants produced equal or greater harvestable weights in some cases with up to 40 % less nutrient solution and this could represent a significant saving in the production costs of hydroponically grown crops.
- AG100 reduced the incidence of Botrytis offering opportunities to save on the cost of chemical disease control and a positive attribute to consumers who would perhaps prefer fewer chemicals applied to crops.
