Spider Mite Control

The glasshouse spider mite or two spotted spider mite Tetranychus urticae is a common pest of protected crops with adult females laying up to 120 eggs in 3 weeks.
Mobile stages suck the contents out of plant cells and produce characteristic leaf damage of white or silvery speckled patches.
Almost all protected crops and soft fruit are vulnerable to infestation.

Torq, an acaricide, can be integrated with biological agents. Use Dynamec for 'hot spots' allowing 7-10 days before introducing predators and as an end of season spray.

HOW IT WORKS: Predatory mite preys on eggs, larval and adult stages of a range of mite species including glasshouse spider mite, citrus mite, fruit tree spider mite, rust mite and thrips. Able to survive on pollen, fungal spores and plant sap in absence of prey and hence can be applied preventatively. Survives high and low temperature but low humidity limits development.
SPECIES CONTROLLED: Glasshouse spider mite and other spider mite species.
