SO-IL Boost pH Equalizer

Well and pond water in the Midwest are often used as carriers in spray solutions. Both sources are usually alkaline and require buffers to be added to acidify the solution. Since water is the basic carrier in agricultural spray operations, growers need to test and know the properties of the water they use. It is suggested that the mix-water be adjusted to no less than a pH of 5.0 and no more than a pH of 6.5.

High pH water can be a problem in the application of pesticides because mineral salts of calcium, magnesium and iron in hard, alkaline spray water combine with pesticides to form solid "precipitates" that settle to the bottom of the tank. These precipitates can clog spray lines and nozzles and can reduce the amount of pesticide available to protect the crop.

Many pesticides break down rapidly in high pH water through a process called alkaline hydrolysis. The fungicide, captan and insecticides/miticides, dimethoate, Imidan, Kelthane, malathion and Omite and most herbicides are particularly affected by alkaline hydrolysis. Pesticide breakdown (hydrolysis) is measured in terms of the half life of a product. For example, if a product is 100% effective when first added to a spray solution and has a half life of 30 minutes, the effectiveness is cut in half (to 50%) in 30 minutes. During the next 30 minutes it is halved again, making it essentially worthless. Once alkaline hydrolysis occurs, it is irreversible.
