Introduction:
OPTICA TRIO is a hormone herbicide which is absorbed by both shoots and roots and rapidly translocated within herbaceous plants.
When herbicides with the same mode of action are used repeatedly over several years in the same field, selection of resistant biotypes can take place.
These can propagate and may become dominating. A weed species is considered to be resistant to a herbicide if it survives a correctly-applied treatment at the recommended dose. A strategy for preventing and managing such resistance should be adopted. This should include integrating herbicides with a programme of cultural control measures. Guidelines have been produced by the Weed Resistance action Group and copies are available from the HGCA, CPA, your distributor, crop advisor or product manufacturer.

Directions for Use:
Important: This information is approved as part of the product label.
All instructions within this section must be read carefully in order to obtain safe and successful use of this product.

Restrictions:

A spray pressure of 2-3 bar is recommended.
Make sure the sprayer is set to give an even application at the correct volume.
Fill the spray tank with half the required volume of clean water and start agitation.
Add the required amount of OPTICA TRIO and continue agitation whilst adding the rest of the water.
Agitate the mixture thoroughly before use and continue agitation during spraying.
Thoroughly wash all spray equipment immediately after use.

Drift:
Do not spray in windy conditions as the spray drift may cause damage to neighbouring crops.
The following crops are particularly susceptible:
Sugar beet, Oilseed rape, Peas, Turnips and most market garden crops including Lettuce and Tomatoes under glass.

Succeeding Crops:
In the event of crop failure for whatever reason following the use of OPTICA TRIO, a period of 90 days should elapse before planting a broad-leaved crop.
Deep ploughing should be carried out prior to planting any succeeding crop.

Application:
Apply using a conventional ground vehicle mounted/drawn equipment.
Ensure that all application equipment is clean.
Traces of OPTICA TRIO can cause harm to susceptible crops sprayed later.
