Dicamba 200

2 PRICE:

3 ACTIVE INGREDIENTS: Dicamba 200 g/L

4 CHEMICAL GROUP: I.

5 RELATED HERBICIDES:

Hormone herbicides.

6 GENERAL DESCRIPTION:

7 APPLICATION METHODS AND TIPS:

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 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 -Acidic water is usually OK. Highly alkaline water may cause loss of efficacy.

11 COMPATIBILITY:

Trace elements.

Zinc sulphate and copper sulphate are antagonistic with dicamba amine. This is caused by ionic reactions and results in a significant loss of efficacy. Manganese sulphate and calcium carbonate (lime) have lesser effects.
