Aqueous dispersions of zineb with different surface‐active compounds were applied to leaves by spraying to beyond run‐off and by leaf immersion. Deposits from leaf immersion cannot be assumed to be similar to those from spraying with the same formulation. The deposits retained with increase of wetter concentration in the formulation were more dependent on the leaf type than on the wetter used. Deposits on lower surfaces of leaves were heavier than on upper surfaces. Comparable tests with Burgundy showed that the effect on the deposit of increasing wetter concentration depends also on the active principle used.
