Tank mix compatibility

Premix and tank-mix compatibility Atrazine is an excellent mixing partner with many herbicides. Compatibility and antagonism problems are rare. In fact, its premix compatibility is so good that atrazine is used more often than any other herbicide as a premix component in com herbicide products. Furthermore, because of the tremendous margin of com safety, mixes do not typically pose a risk for increased crop injury. 

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. 

Tank mix compatibility. Some chemicals only have limited compatibility with other pesticides this can be due to a problem with the formulations or with the activity of the chemical being affected. To get optimum weed corrtrol in some crops mixtures of chemicals are required or sometimes the use of sequences/ stacking (products applied in close succession) is mote effective.

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). 

Based on these data, BALAN Dry Flowable appears to be compatible with each of the agrichemicals with which it may be tank mixed, since there was little residue retained on the 50-, 100-, and 325-mesh screens. 

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). 

When BALAN/Emulsifiable Concentrate D tank mix was tested at a rate of 5 gal/acre, the system was unsuitable for application (Table VII). However, when the spray volume was increased to 10 gal/acre, the tank mix was compatible. As a result, the the BALAN Dry Flowable label recommends that tank mixes be applied at a minimum of 10 gallons/acre. 

A formulation can contain more than one active ingredient to increase the efficacy range per application. This reduces labor time, because fewer sprajdngs are necessary than with separate spra3dngs of single pesticide formulations. A similar result is achieved when several products are mixed directly before application (tank mixes). However, the products of the different formulations must be compatible. For instance, oil- and water-based products cannot be mixed and would lead to phase separation. Chemical incompatibility can occur as result of reaction of acids with bases or hydrolysis of pH sensitive compounds. 

Flexibility of Use. Products based on Bt have been successfully incorporated into pest management programs in agriculture, forestry and vector control. This is largely due to the fact that the Bt delta endotoxin and spores are relatively stable when tank mixed with conventionally used fungicides, insecticides and spray adjuvants. In addition, most commercial Bt formulations have been designed to optimize shelf life, as well as physical compatibility with other agricultural chemicals and application systems.

In recent years, the addition of tallow has moved directly to dairy and beef feed lots. Small, heated, insulated tanks have been developed to receive and hold fat shipments (Figure 7). As described earlier, beef tallow is the most compatible fat for ruminants. It may be sprayed or flowed, at 2-3% of dry matter onto rations of chopped hay, other roughages, grains, or concentrates while in the mixer, or top-dressed on hay or other forages. Feed mixing operations like these require a positive displacement pump, like a Moyno or gear pump with variable-speed drive set to deliver a known amount of fat within a specific time period. As an alternative, mixers in feed mills can be mounted on load cells and equipped with controllers to stop the flow of fat when the desired weight has been added.
