Agricultural formulations applications

In particular, the low application rates used for these compounds in agricultural formulations are an important positive factor which should contribute significantly to the elimination process, and to the minimisation of any potential negative accumulative effects. 

Comer et al. (2) therefore evaluated the effect of exposure to carbaryl (1-naphthyl methylcarbamate) on formulating plant workers and on workers applying carbaryl to fruit orchards with a tractor-drawn air-blast sprayer. However, information was still needed on the persistence of carbaryl in apple orchards and on the resultant exposure of workers who re-enter treated orchards. Further, no studies had been done on other types of crops. The present study was undertaken to determine the exposure of agricultural workers to carbaryl as a function of type of formulation, application equipment, application method, and type of work performed (i.e., mixer-loader, applicator, flagman, bystander, and apple thinners). 

Tables 15.6 and 15.7 lists the various hydrocarbon solvent blends marketed by Shell Chemical. The blends with boiling points ranging from 61 to 204°C find use as solvents in adhesives, agricultural formulations, automotive undercoating, cleaning and polishing formulations, cosmetics, drugs and pharmaceuticals, inks, paints, varnish, lacquers, paper coatings, resin and plastic applications, textile coatings, printing, and other miscellaneous uses.

SURFADONE LP surfactants are unique, multifunctional nonionic surfactants. Both of these surfactants combine the ability to complex many polar materials with excellent wetting, surface tension reduction and solvency. Applications include personal care, specialty cleaner and agricultural formulations. 

Typical Applications Detergents, textiles leather processing, agricultural formulations. Dispersants. 

Typical Applications Detergents, agricultural formulations, oil well drilling, leather processing, paints. 

Typical Applications Agricultural formulations, high temperature detergents, textiles, polymerization. General purpose emulsifier, stabilizer. 

Coformulants are defined as any material other than the active ingredient which is added to a pesticidal active ingredient prior to packaging for sale to an end-user. This category includes all the items commonly employed by formulations chemists - solvents, solid diluents and carriers, surfactants, dyes, and aerosol propellants. Minerals in agricultural chemical applications will invariably be used as coformulants and not as adjuvants. 

Triazole derivatives (diniconazole-M, epoxiconazole, fluhinconazole etc.) are widely used in agricultural practice as fungicides. The low application rates of these formulations require specific conditions for identification of residual quantities in different objects. 

Compound A to Compound B were made to a mature wheat canopy while six sequential applications of a formulation with a 1 1 ratio of Compound A to Compound B were applied to mature apple trees. These studies closely mimicked actual agrochemical use patterns in terms of application rate and timing, application volume, irrigation, and other key agricultural practices. 

More effective and safer insecticides are needed, in spite of the extensive progress made in recent years. The chemist should familiarize himself with the needs in the agricultural, storage, household, livestock, and industrial fields. The weak and strong points of the products in use should be understood. Some of the commonly used products need better formulations, or better methods of application with the use of more effective supplements. Better products should replace some of those now in use. Statistical evidence of ample potential should be available before work on a problem is begun.
