Reducing fines from an agricultural spray dispensed from a nozzle is provided in the disclosed methods. The agricultural spray comprises water, an agricultural composition such as a pesticide, at least one oil emulsion drift reduction adjuvant, and at least one spontaneous emulsion drift reduction adjuvant. The agricultural spray exhibits fewer fine droplets having a diameter less than about 105 μm, about 150 μm, and/or about 210 μm compared to an agricultural spray neither or only one of the oil emulsion drift reduction adjuvant and the spontaneous emulsion drift reduction adjuvant.

An object of the present invention is to provide a layer for suppressing permeation of soil moisture that has a low environmental load and can be easily constructed, and a method of forming the same. The method of forming a layer for suppressing permeation of soil moisture comprises a step of spraying coagulant for a natural rubber latex over a target soil and then spraying a natural rubber latex over the target soil, and repeating the step twice or more.
