1 These rates are suggested for trees with a settled cropping history. Chemically thinning a first crop tree or immature trees is considered very risky.
2 Sevin XLR is 43% active ingredient and contains 480 g or approximately 0.5 kg of carbaryl per litre. 1 L of Sevin XLR is roughly equivalent to 1 kg of Sevin 50 W.
3 Sufficient water volumes must be used to thoroughly wet trees. For actual amount of NAA, refer to the label.
4 Consult [Suggested Rates of MaxCel or Cilis Plus to Use With or Without Sevin XLR](/supporting-information/apples/thinning-and-plant-growth-regulators/suggested-rates-of-maxcel-or-cilis-plus-to-use-with-or-without-sevin-xlr) to determine the actual ppm benzyladenine (BA) being applied. Concentration of BA should be no less than 50 ppm to be effective.
