ATILLA is an insecticide based on potassium hydrogen carbonate which gives a reduction of pear suckers in pear orchards. It repels adults and kills all larvae stadia of the pear sucker. Thanks to its particular properties, ATILLA can also reduce sooty moulds on leaves, buds, stems and fruits.

Potassium hydrogen carbonate is an active ingredient for which no resistance is known and for which no maximum residue limit (MRL) needs to be set.

Applications to pears against the pear suckers

ATILLA can be used from bud swelling until after harvest in pears. Do not apply ATILLA during flowering.

Dose rate: 8 kg/ha. Maximum 9 applications per year with a spray interval of 7 days, which can be reduced down to 5 days in case of heavy rainfall. This dose rate is for use on trees of 3.0 to 3.5 metres height at full crop canopy. Where trees are significantly taller than 3.5 m, efficacy is likely to be reduced.

Water volume: ATILLA can be sprayed from 200 to 1000 L/ha.

Pre-harvest interval: none

Where tree height and/or canopy density is reduced, the dose and water volume should be adjusted in accordance with an appropriate dose adjustment scheme. Consult Globachem or your specialist advisor for further information. Further information on the PACE scheme is available from the HDC, or see the HDC leaflet (Orchard Spraying: Opportunities to reduce rates) available on the CRD website.

Consult processor before using on crops being grown for processing.

ATILLA can also be used on young pear trees.

A mild chlorosis on leaves may be observed that tends to diminish over time when the applications cease. This mild chlorosis has however no impact on yield or the quality parameters.

An adjuvant is not needed. Do not change the pH of the spray solution since it may cause a reduced efficacy.
