  • the agrochemical composition has a reduced concentration of preservative; that the antimicrobial effect of the preservative in the agrochemical composition is very high even at a reduced concentration; that the agrochemical composition continues to be easily formulated; that the usual agrochemical formulation adjuvants can be used; that the usual agrochemical application techniques such as spraying or pickling can be used; and that the insecticidal or rodenticidal effect is not impaired by undesirable odor or taste.
  • Preservative An aqueous formulation of 2.35-2.65 weight percent 2-methyl-4-isothiazolin-3-one (MIT) and 2.35-2.65 weight percent 1,2-benzisothiazolin-3-one (BIT), commercially available from Thor as Acticide® MBS. The manufacturer recommends using a concentration of 0.2-0.4% by weight in aqueous products.
  • MIT 2-methyl-4-isothiazolin-3-one
  • BIT 1,2-benzisothiazolin-3-one
  • suspension concentrate A 400 g / l pyrimethanil (fungicide)
  • SC B Suspension Concentrate B
  • F Suspension Concentrate B
  • fungicide 150 g / l pyrimethanil
  • each of the samples 1 to 16 was inoculated with a germ mixture consisting of various bacterial species (such as Bacillus subtilis, Escherchia coli, Pseudomonas aeruginosa, Staphylococcus aureus), homogenized and incubated at 23 ° C.
  • the number of bacteria per gram of sample (cfu / g) was determined immediately and after 24, 48 and 72 hours. In each case, about 1 g of the loaded sample was weighed exactly and spiked out in appropriate dilutions on 2% malt extract agar. The dilution of the loaded sample was carried out by homogenization with sterile water. To detect the bacteria, the malt plates were incubated for 3 days at 23 ° C. The control without preservative and without PDO showed a very high bacterial count of well over 50,000 cfu / g. The results are summarized in Table 1.
  • Example 2 The investigation was carried out as in Example 2, wherein instead of suspension concentrate A now suspension concentrate B was used. The results are summarized in Table 2. It has been shown that the addition of 1, 2-pentanediol to the agrochemical formulation, the effect of the preservative could be increased.
