The fungicide interactions in the combinations are calculated according to COLBY method.
  • Example B-3 Action against Pyricularia orvzae
  • Conidia of the fungus from cryogenic storage are directly mixed into nutrient broth (PDB potato dextrose broth). After placing a (DMSO) solution of the test compounds into a microtiter plate (96-well format) the nutrient broth containing the fungal spores is added. The test plates are incubated at 24 0 C and the inhibition of growth is determined photometrically after 72 hrs. The fungicide interactions in the combinations are calculated according to COLBY method.
  • Example B-4 Action against Alternaria solani (early blight)
  • Conidia -harvested from a freshly grown colony- of the fungus are directly mixed into nutrient broth (PDB potato dextrose broth). After placing a (DMSO) solution of the test compounds into a microtiter plate (96-well format) the nutrient broth containing the fungal spores is added. The test plates are incubated at 24°C and the inhibition of growth is determined photometrically after 48 hrs.
