situation. Environmental conditions Optimal temperatures for Mirical are above 20°C/68°F, lower temperatures slow down the development of Macrolophus pygmaeus
It is preferable to use white of light coloured bags/cups at temperatures above 20 °C.
root tips are affected. They become black and start to rot internally. Just above the damaged area, the roots produce large numbers of new branches. This
inoculum Sowing winter crops early in the fall when temperatures are still above 15°C at the critical first 11 days reduces the risk of infection by Triticum
sporangia or by zoospores produced in the sporangia. For germination on above-ground plant parts, leaf wetness is required. Dispersal is by wind and rain
effective at temperatures between 13 and 27°C (55 and 81°F) and not effective above 30°C/86°F. Phytoseiulus persimilis is sensitive to relative humidity below
is less common but can develop very dry seasons. Bleached ears often show above the point of infection around the milky ripe stage (GS 75). Later infections
lateral ventilation openings Attach traps to wires or sticks at max. 30 cm above the crop and adjust height when plants are growing Do not place traps in-between
the crop. If the crop is low, make sure the traps hang at least one metre above the ground. In taller crops, the traps can be placed in the crop Protect
effective between 20 and 25°C (68 and 77°F). Not effective at temperatures above 30°C/86°F. Combined use Can be used in combination with other aphid biocontrol
