Where such products aim solely at improving the plants' nutrient use efficiency, nutrient availability, tolerance to abiotic stress, plant quality traits, or yield 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 in razpoložljivost hranil, povečati toleranco na abiotski stres, izboljšati kakovostne lastnosti rastlin ali pridelek, so po naravi bolj podobni gnojilnim proizvodom kot pa večini kategorij fitofarmacevtskih sredstev.
