A water‐soluble granule containing 750 g/kg ethametsulfuron methyl for control of certain broad‐leaved weeds in winter and spring oilseed rape and fodder rape.

Weed control
SALSA contains ethametsulfuron methyl, a sulfonylurea (ALS inhibitor) herbicide and is most effective if applied when the weeds are small and actively growing. Good spray cover of the weeds must be obtained for best results. Susceptible plants cease growth almost immediately after application and symptoms can be seen about two weeks after application. Weed control may be reduced when soil conditions are very dry. The susceptibility rating of the weeds in the following table refers to post‐emergence application with good spray cover and growing conditions.

Resistance
This product contains ethametsulfuron methyl, an ALS inhibitor, also classified by the Herbicide Resistance Action Committee as ‘Group B’.  
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 resistant to a herbicide if it survives a correctly‐applied treatment at the recommended dose. Development of resistance within a weed species can be avoided or delayed by sequencing or tank‐mixing with suitable products having a different mode of action. A strategy for preventing and managing resistance should be adopted. The Weed Resistance Action Committee has produced guidelines and copies are available from your distributor, crop adviser or product manufacturer.
To prevent the build‐up of resistant plants, SALSA should not be used as a sole means for control of chickweed or mayweed. Where these are present, SALSA should be used only in tank‐mixture or in sequence with herbicides with non‐ALS modes of action. In addition, the use of cultural methods of control and non‐ALS herbicides within the rotation will help lessen the risk of resistance development.

Crops
SALSA can be used on all varieties of winter and spring oilseed rape and fodder rape between the growth stages given below.  

Dose
Apply SALSA at 25 g/ha. An approved non‐ionic adjuvant should be included at 100 ml per 100 litres of water (0.1% v/v).

Timing
SALSA may be applied in the autumn or spring from the cotyledon up to and including the 8 leaf stage of crop growth.

Following crops
Cereals may be sown in the same calendar year of harvest of an oilseed rape crop treated with SALSA.
Cereals and maize, may be sown in the spring of the year following harvest.
In the event of crop failure for any reason, wheat or barley can be planted. Prior to sowing, soil should be ploughed and cultivated to a depth of at least 15cm.

Volume and application
BEFORE USING SALSA, SPRAYING EQUIPMENT MUST BE CLEAN AND FREE FROM CONTAMINATION WITH OTHER PESTICIDES. Application should be made in 100‐300 litres of water per hectare to give good spray cover of the weeds. The higher volume is recommended when crops are thick or weed growth is dense. Use a conventional field crop sprayer at a pressure of 2 ‐ 3 bars and apply as a MEDIUM spray (as defined by BCPC). Care should be taken not to overlap spray swaths.

Mixing
Quarter fill the spray tank with clean water, start the agitation and add the required quantity of SALSA directly to the tank without prior creaming.  Continue agitation while topping up the tank and while spraying.
