How to use Feltiline a
Place the tub in the shade on the ground close to spider mite colonies, but away from irrigation systems. Make a hole in the filter paper lid. Use 1 tub per localised outbreak. Repeat 4 times at weekly intervals. Use 1 tub per 1000 sq.m. for more generalised attacks.
Continue release until cocoons appear under leaves (22-25 days at 22°C).
Diapauses in short day-lengths.Will not disperse if adequate food is present: ensure proper distribution in the greenhouse. Do not use in presence of generalist predators like Macrolophus or Nesidiocoris.
Avoid regular use of sulphur which can affect the survival and development of Feltiella.
