2,4-D amine plus Dicamba
See individual components, 2,4-D amine 500 and Dicamba, for general information.
Rates quoted in HerbiGuide are based on a 1:1 mixture. For example, 1000 mL is equivalent to 500 mL of 2,4-D amine plus 500 mL of Dicamba200 amine.
4 CHEMICAL GROUP: I.
10 WATER QUALITY:
Hard water - There may be a slight loss of activity due to ionic bonding in very hard water.
Colloids - Some loss of 2,4-D amine activity as the amount of clay in the water increases. If it is difficult to see a coin on the bottom of a 10 litre bucket full of water then the water should be cleared or an alternate source found.
pH -Highly acid or alkaline water may cause loss of efficacy.
Zinc sulphate and copper sulphate are antagonistic with 2,4-D amine. This is caused by ionic reactions and results in a significant loss of efficacy. Manganese sulphate and calcium carbonate (lime) have lesser effects.
