Lenns™ Herbicide Product Overview & Infographic

Learn about Lenns™ – a revolutionary herbicide for pre- as well as post-emergence control of certain difficult-to-control weeds in stone fruit.
Lenns™ Infographic

Lenns™ is a unique combination herbicide that will provide pre-emergent as well as post-emergent control of especially difficult-to-control weeds, like fleabane and buckhorn plantain, in stone fruit. Before Lenns™ there were only post-emergent options available. 

Which crops can Lenns™ be used on?

  • Stonefruit 

Is it safe?

Handle with care. Avoid contact with eyes, skin and clothing. Store in the closed, original container in a locked, cool, well-ventilated area, away from direct sunlight. Do not mix, store or apply in galvanised steel or unlined steel containers (the exception being stainless steel), as a reaction will produce combustible hydrogen gas. Store away from food, feeds, seed and other agricultural chemicals. Read the full list of precautions on the label.


Lenns™ is classified as a HRAC group code 9 and 12 herbicide. For further advice on the prevention of herbicide resistance, contact your ADAMA field agent.

Which weeds?

Lenns™ provides post- and, more importantly, residual pre-emergent control of especially difficult to control weeds.

  • Flax-leaf fleabane/hairy fleabane/asthma weed – Conyza bonariensis (syn Erigeron bonariensis)
  • Buckhorn plantain – Plantago lanceolata
  • Wild/prickly lettuce – Lactuca serriola
  • Additional weeds not listed may also be controlled, but the registration holder will not accept responsibility for the control of weeds not listed on the label.

NOTE: Use and apply only as directed on the Lenns™ label.

Mixing instructions

  • Half-fill the spray tank with clean water. 
  • Shake Lenns™ container well prior to opening, then add the required quantity to the spray tank while agitating. 
  • While agitating, top-up the spray tank with water to the required volume. 
  • Ensure constant effective agitation during mixing and application. 

NOTE: Only prepare enough spray mixture for one day’s use. Spray mixture should not be allowed to stand overnight.

If tank-mixing Lenns™ with other products, a physical compatibility test must be conducted prior to application. To determine physical compatibility, pour the required proportions of the product(s) into a suitable container. After mixing, wait for 30 minutes and check to see if the product remains in mixture. Products that remain in mixture, are considered physically compatible.

Usage instructions

Consult the Lenns™ label for comprehensive usage directions and restrictions, some of which include:

  • Apply Lenns™ in spring, after weed emergence, directing the application to the foliage and immature stems of actively and vigorously growing weeds. 
  • Refrain from sprinkler irrigation for 12 hours after application and do not apply Lenns™ when rain is expected within six hours of spraying, or in windy conditions. 
  • Do not apply Lenns™ to orchards that are under stress from drought, excessive heat, frost, water logging or herbicide damage. 
  • Prevent spray drift onto or contact with foliage and fruits of cultivated crops and young stems of trees that have not yet become woody. 
  • To minimise the risk to aquatic life, do not spray within 2 m of the top of the bank of any water or to the top of a ditch even if dry at the time of application. 
  • Do not apply LENNS™ more than once in 18 months. Diflufenican can accumulate in the soil when LENNS™ or other products containing diflufenican are applied in successive years. 
  • Do not add any wetting agent or adjuvant oil before consulting ADAMA South Africa (Pty) Ltd.
