Paraquat plus Simazine

Rates quoted in HerbiGuide are for a 1:1 tank mix of Paraquat 250 plus Flowable Simazine 500. A rate of 1000 mL is equivalent to 500 mL of Paraquat 250 plus 500 mL of Flowable Simazine 500. Similarly a rate of 1000 mL is equivalent to 625 mL of Paraquat 200 plus 278 grams of Simazine 900 granules.

This mixture is synergistic which means that lower rates of the mix are equivalent to higher rates of the individual components.

See individual products for more information.


Water Quality

Hard water - There may be a slight loss of paraquat activity due to ionic bonding in very hard water.

Colloids - Significant loss of paraquat 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 paraquat efficacy.
