The application of TRILOGY to crops suffering from stress may lead to a check to growth from which the crops may not recover and in some cases crop losses may occur. Crops suffering from nutrient deficiencies such as nitrogen, copper, manganese, magnesium or lime may be adversely affected when sprayed with TRILOGY. Growers should ensure that nutrient status of the soil is correct before the crop is drilled.
If the temperature is 21°C or is likely to rise to this temperature for the period of twenty-four hours after application do not spray as serious crop damage may occur.
If substantial day to night fluctuations in temperature occur shortly before or after the application of TRILOGY crop growth may be checked.
The interval between preparation of the spray mixture and completion of spraying should be kept to a minimum, certainly no longer than 2 hours. Any longer may result in crystalisation, particularly if the water temperature is below 5°C.
Avoid drift to areas outside those being sprayed, having due regard to the prevailing weather conditions and spray quality being used. TRILOGY may be used on all types of soils, though residual activity may be reduced on those with more than 5% organic matter.

All commercially grown varieties of sugar beet, fodder beet and mangels may be treated with TRILOGY.
The first application of TRILOGY should be made after the majority of the crop has reached the fully expanded cotyledon stage.
The effect of ‘TRILOGY’ on seed germination from treated beet seed crops has not been investigated.
Use a MEDIUM spray (BCPC classification) and dilute with 100 – 300 litres water/ha.

First application:
Timing: At the first flush of weeds, preferably when they are not larger than the fully expanded cotyledon stage.
Rate of use: 2.0 litres product/ha.
Second and third applications:
Timing: At the second and third flush of weeds, but not before 5 days after a previous application.
Rate of use: 2.5 litres product/ha.

Half fill the spray tank with water and commence agitation. Add the tank-mix partner first and allow complete dispersion. Add the required amount of TRILOGY to the sprayer tank and fill up with water whilst agitating. Use immediately. Continue agitation until spraying is complete.

For further information on tank mixing please refer to the website (

Beet crops may be sown at any time after the use of TRILOGY, any other crop may be sown 3 months after the last application. Ploughing with a mould board to a minimum depth of 15cm (6”) should precede preparation of a new seedbed.
