insecticide-tolerance
Insecticide-tolerance describes a plant's ability to withstand or remain unaffected by insecticide applications through genetic or physiological resistance mechanisms. In plant science, understanding insecticide-tolerance is crucial for developing effective crop protection strategies, predicting pesticide efficacy over time, and breeding crop varieties that balance pest suppression with tolerance to agricultural chemical treatments.

A natural compound called spermidine helps strawberries resist the harmful effects of dinotefuran insecticide by blocking the insecticide from entering plant tissues. This discovery could enable safer, more resilient strawberry production with reduced chemical accumulation.
Spermidine significantly reduces dinotefuran accumulation in roots, stems, and leaves, with particular effectiveness in preventing insecticide migration to leaves
Spermidine improves strawberry growth under insecticide stress by enhancing photosynthesis, increasing osmotic substances, and reducing oxidative damage
Spermidine competitively occupies ABC transporter channels (subfamilies C and G) that normally transport dinotefuran, blocking the insecticide's uptake and accumulation
