Push-back on chemicals for crop protection is increasing from legislators, consumers and supermarkets.
Although the range of biological products to use instead is expanding rapidly, farmers still lack the knowledge and confidence to use them, while regulators are holding back progress on more advancements.
At a Woolworths suppliers’ day held in Mbombela, Mpumalanga, in April, the supermarket group outlined its goal to have all fresh produce attain a zeroresidue status by 2035. This requires a more considered use of crop protection than the current system of maximum residue levels (MRLs), where products can still leave residues as long as they are within prescribed amounts.
