MiXinG anD aPPlicaTiOn MeThODS Hotshot Herbicide can be mixed with water only. Mix only sufficient chemical for each day’s use and avoid storing mix. Half fill the spray tank with water and add the required quantity of Hotshot and complete filling. Agitate continuously to ensure thorough mixing before and during application. Tank mixtures: wettable powder or dry flowable formulations (e.g. water dispersible granules such as metsulfuron) should be added to the spray tank first, followed by suspension concentrates (flowables), water soluble salts and then emulsifiable concentrate formulations (e.g. 600 MCPA). Hotshot is an EO formulation, which is similar to an emulsifiable concentrate formulation. Add spraying oils and surfactants (wetters) last, if required. 14 Spray recommendation guide Ground application Minimum spray volume 80 L/ha Nozzle type Hydraulic nozzles Spray quality Medium droplets Where possible do not spray when Temperature > 28˚C, relative humidity
