Integrated weed management has a synergistic effect – more bang for your buck! When there is a competitive crop growing, the herbicides work better and harvest weed seed control works better. Many little hammers to keep weed numbers low pays off. 🔨 🔨 🔨

Resistance to DIM chemistry is due to target-site resistance – Peter Boutsalis explains why it has taken longer to ‘arrive’ than is usually expected for herbicides that target a single site within the weed.
Understanding resistance to DIM herbicides - WeedSmart
Dr Peter Boutsalis says clethodim resistance can’t be ignored. Ryegrass plants that survive must be controlled with other tactics.

Wondering whether new sprayer gear is worth the price? 🚜 Peter Newman has run the figures.

He says that, generally, optical sprayers will pay for themselves when a grower is doing at least one pass for summer weed control and spraying broadleaf weeds in cereals.
