Thrip Control:


Thrip damage on Chrysanthemum.	Adult Thrips tabaci on cucumber leaf.	Thrip larvae and adult. (Banded-winged palm thrips (Parthenothrips dracaenae) a common pest on interior atrium plants, botanic gardens and conservatories.

Two species of thrips are commonly found on protected crops: Western Flower Thrips (WFT), (Frankliniella occidentalis) and Onion or Tobacco Thrip (Thrips tabaci). Larvae and adults graze the leaf surface causing extensive 'silvering'. WFT can also transmit Tomato Spotted Wilt Virus on chrysanthemums and many other crops. Other species of thrips are also being found, particularly on specimen plants. If in doubt send a sample to Fargro.
There is a pheromone trap for monitoring of Western Flower Thrips (WFT).

WHEN TO USE: Ideal to control established thrip poplulations on a range of plants and can be used alongside Conserve and other biologicals.
RATE OF USE: 0.5 to 1 per m² every 2 weeks until established. Consult Fargro as to the best species to use on your crop.

SPECIES CONTROLLED: Adult female Western Flower Thrips. Larvae are not always attacked but pupae frequently are. Also controls leafminer.
WHEN TO USE: At any time of the year, ideal at temperatures above 16^oC. Do not use under strong lights or when the sprayed crop is likely to dry within 3 to 4 hours. A series of 4 or 5 weekly sprays is best to control a thrips population. Nemasys F can be used alongside Conserve and several other pesticides for a wider range of activity.
RATE OF USE:
Preventative: 50 million per 400m² or 250 million per 2000m².
Standard control: 50 million per 200m² or 250 million per 1000m².
