Root ticks

To them concern some different kinds of ticks, unites which that they damage underground parts of plants. Among root ticks is more often meet Bulbous root tick (Rhizoglyphus echinopus) and Bulbous tick (Steneotarsonemus). These ticks make harm first of all to bulbous plants (to gladioluses, hyacinths, tulips, orchids, etc.). Ticks have very small sizes - the Bulbous root tick approximately 0,5 - 1 mm, the wide oval body of light yellow colour narrowed by the end, and four pairs feet. The bulbous tick is hardly larger - to 1,5 mm in length, the oval body and two pairs feet has. They eat bulb fabrics, postponing there eggs in a large quantity - about 300 eggs from one female of the bulbous root tick. Thus at an initial stage of defeat are visible the eaten away places and courses of ticks, however gradually ticks gnaw all bulb. The damaged bulb will easily collapse in hands or will break, in it all internal fabrics are eaten away, there is only a white dust, and ticks are visible not to an aided eye. Root ticks actively breed and develop in a wide range of temperatures - from 10 to 25°C and even above, at change of conditions, they don't perish, and run into a condition of diapause. Root ticks especially strongly breed at high humidity of air. Therefore one of measures of preventive maintenance of occurrence of root ticks is the storage of tubers, bulbs and root crops in a dry cool place, at humidity not above 60 %.
Struggle measures: Before landing attentively to examine bulbs. Promotes occurrence of root ticks of a condition of the raised humidity of soil. Thus it isn't necessary to water the plant less, than it demands, it is necessary not to suppose stagnation of water in roots, i.e. to do a good drainage and to merge water from the pallet. The amazed bulbs and roots of plants maintain or water with a solution of system insection (for example, neoron, actellic, apollo).
