sentence: Therefore , only information on viable residues i.e. CFU per g or kg plant commodities at harvest is needed to demonstrate that the threshold of 1 × 10 CFU / g edible plant commodity is not exceeded.To ensure this , the setting of a PHI may be needed because available experimental data from residue trials in greenhouse lettuce and peppers ( up to 1.78 × 10 CFU / g 2 days after treatment following three applications of 9.82 × 10 CFU / ha and 1.2 × 10 CFU / g 5 days after treatment following three application of 1.6 × 10 CFU / ha , respectively ) , and theoretically calculated estimated counts ( based on a total application of 1.5 × 10 CFU / ha ) on treated tomatoes of maximally 9 × 10 CFU / g ( 3 × 10 CFU / g after the first application ) for Bacillus thuringiensis subsp. kurstaki strain PB 54 demonstrate that counts at harvest may be close to or even exceed this threshold.A study on cucumber in the greenhouse was conducted with Bacillus thuringiensis subsp. kurstaki strain PB 54 with one application equivalent to 50 % of the maximum applied CFUs per hectare of the representative use and at BBCH 89 instead of BBCH 99 .
