Tank-mix testing and compatibility

There are six papers la this section. They deal with biological insecticide formulations (Ward), water dispersible granules (Wright and Ibrahim), analysis of formulations for quality control and identification of toxic contaminants (Plimmer), identification of surfactant metabolites (Stolzenberg et al.), electrostatic spraying (Law) and compatibility and tank-mix testing (Tarwater). 

It is one thing to commit to a given discovery procedure once one feels comfortable with the ability to interpret or translate a response to possible field application. It is another matter entirely to "go all the way" in development stages to prove efficacy and utility human and environmental safety and acceptance by the farmer or grower. Many tests are required to have satisfaction in results obtained efforts must include variation in rates, timing,spray, dilution, formulation or tank mix compatibilities, varietal responses, optimal environmental conditions, geographical dependencies and season long and carry-over observations. 

The observations made were 1) the uniformity of the mixture after certain time intervals and 2) the number of inversions required to resuspend the settled material. This gives an indication of the utility of a mixture after being left in a spray tank for an extended period of time. These data are given in Tables III and IV. These data indicate that BALAN Dry Flowable is compatible with the three liquid fertilizers tested and that no compatibility agent is required when BALAN Dry Flowable is used alone. In the case of tank mixes with other herbicides, the compatibility agents sometimes increase the uniformity of the mixture. For an example, see BALAN/Emulsifiable Concentrate D with and without Compatt (Table IV).
