Some perennial crops such as fruit orchards can attract K-selected pests. In these circumstances ecological theory predicts slower-acting therapeutic agents could be used, but that trying to prevent pest build-up by introducing competitors is unlikely to be successful. Factors that naturally limit pest populations Physicochemical conditions The physicochemical conditions of an environment help determine the occurrence and abundance of all living things including the properties of soil or water (pH, salinity), climate (temperature, rainfall, radiation) and weather.
Invasive weeds are plant species that have been introduced to an area, region or country where they are not indigenous and which subsequently become established and spread. 3.
