Abstract

The invention relates to an aqueous formulation that reduces the damage caused by spring frosts in plants, which comprises: (a) 0.001–2% by weight PVA micro/nanoparticles having a molecular weight of 10,000–100,000 g/mol and 1–20% acetate groups; (b) 0.0001–0.4% by weight stabilising agents; (c) 0.0005–0.05% by weight category IV adjuvants; (d) 0.00025–4% by weight emulsifier; (e) 0.003–6% by weight sodium hydroxide; and (f) 0.0065–13 % by weight hydrochloric acid at 37% weight/weight and 1.18 g/mL density. The invention also relates to a process for producing the aqueous formulation, and to uses.
