Where such products aim solely at improving the plants' nutrient use efficiency, tolerance to abiotic and biotic stress, or crop quality traits, they are by nature more similar to fertilising products than to most categories of plant protection products.
Kadar je namen takih proizvodov samo izboljšati učinkovitost izrabe hranil v rastlinah, povečati toleranco na abiotski in biotski stres ali izboljšati kakovostne lastnosti kmetijskih rastlin, so po naravi bolj podobni gnojilnim proizvodom kot pa večini kategorij fitofarmacevtskih sredstev.
