figures were obtained from a commercial trial done on field
tomatoes. The control was on 10 hectares, whilst the BIOSTART® was
just over 12 hectares. Both areas had the same fertilisation
programme. |

| RESULTS OF ACADEMIC
TRIALS USING BIOSTART® |
| c |
| The following
growth stimulation trials were conducted at the Plant Pathology
& Microbiology Department, University of Natal,
Pietermaritzburg. All plants were placed in a covered tunnel, with
watering and fertigation by a standard hydroponic solution. At
maturity, the plugs were removed and weighed, then dried and
reweighed. |

Whilst Microbial
Solutions (Pty) Ltd has an abundance of information and trials results
from overseas, we have endeavoured to obtain as much information as
possible on the effects of BIOSTART® in South Africa under our own
unique field and nursery conditions. In addition to the results detailed
below, we have many more reports from South African end-users, as well
as a host of photographs available showing the effects of BIOSTART® on a
variety of crops and in different circumstances.
Should you as a
grower not object to sharing information and have any information or
figures which could be pertinent to other BIOSTART® users, we would
appreciate your input.

Two years of

Stellenbosch with exceptionally good results.

The results were
beyond all expectations. As the BIOSTART® B. subtilis results
were no better than the BIOSTART 2000 and it does not have either the
growth stimulation or the nematacidal effects, it was decided to
continue with the BIOSTART 2000 only in the following season. As methyl
bromide is considered the standard for control of this disease complex,
it was decided to include this substance in the next trial to compare
against the BIOSTART.

This season's trials were conducted in three known contaminated
sites.

The BIOSTART® gives
a 105% increase in growth over the controls and a 71.4% over the methyl
bromide.
These results give hope for the future to farmers as not
only is methyl bromide due to be removed from the market, but increased
use of biological controls which leave no residues, combined with a
better balance of the use of traditional chemicals, are unquestionably
the future for agriculture.
