Pinatoro

Pimelea prostrata, known commonly as Pinatoro, belongs to the Thymelaeaceae family. It is a perennial prostrate shrub or herb characterized by its low-growing form and its ability to spread vegetatively, which allows it to colonize open habitats and pasture areas quite effectively.

This species is primarily distributed in regions with temperate climates, notably within New Zealand. In agricultural settings, it is often found in permanent pastures, meadows, and perennial forage crops, where it competes aggressively for space, nutrients, and sunlight against desirable forage species.

The biology of this weed is defined by its branching, mat-forming stems that root at the nodes, making manual removal or simple cultivation difficult to execute. It flowers during the spring and summer seasons, producing small seeds that facilitate its dispersal across grazing land and fields.

The economic impact of Pimelea prostrata is primarily observed in the suppression of productive forage grasses. By forming dense mats, the weed restricts light penetration and nutrient availability, which significantly reduces the yield and nutritional value of hay and pasture used for livestock production.

Control strategies for this weed require an integrated approach. Agrotechnical methods include intensive grazing management, periodic harrowing, and mowing to exhaust the plant's resources. Chemical control involves the application of selective herbicides targeting broadleaf weeds, which must be carefully timed to ensure maximum efficiency without harming the associated crop species.
