Mechanism of Action

The active substance of such preparation as ROME suppresses cell division at the growth points of shoots and roots in the sensitive weeds. It is mainly absorbed by leaves. Absorption through the root system depends on the soil moisture and is limited by time.


Most-sensitive weeds:

Common bastard oat, green valley grass (Sorghum halepense) (seeds and rhizomes), blindweed (Capsella bursa pastoris), field mustard, crossweed (Diplotaxis muralis), buttercup (species), chickweed satin flower (Stellaria media), black bent/grass, wild poppy, field mint, foxtail grass (species), Canada thistle (Cirsium arvense), multiflorous ryegrass/darnel (Lolium), barnyard grass (Echinochloa crusgalli), hairy crabgrass (Digitaria sanguinalis), common couch grass (Agropyron repens), catchweed bedstraw (Galium aparine), brown-corn millet (Panicum miliaceum), annual mercury (Mercurialis annua), chamomile (species), wild radish, common fumitory (Fumaria officinalis), annual bastard cabbage/common giant mustard or turnip weed (Rapistrum rugosum), sunflower dead beans (a phase when 2-4 leaves appear), timothy / herd grass (Phleum gen.)

Recommendations for Use

Application Features

Spray solution should be prepared immediately before spraying. Before preparing the spray solution, it is necessary to measure the required volume of the preparation per one sprayer filling up. The preparation can be entered at a stage when corn/maize plants are in the phase of 1-6 leaves. No restrictions on crop rotation due to rapid degradation in the soil. It is not recommended to use the preparation when culture plants overgrow (more than 7 leaves).

Spray Material Consumption Standards



The preparation is more effective when entered as single. It may be mixed with 2.4-D-based preparations. It is advisable to prepare a test mixture when it is expected to use a combined mix.

Precautions in Use

It is not recommended to use the preparation at temperatures below +10°C and above 25°C. It is forbidden to use ROME in corn/maize fields for 14 days before or after they have been treated with organophosphorus insecticides.
