Over time, weeds have developed resistance to current herbicides, allowing weeds to flourish.
Weed resistance and tolerance to herbicides build over time with repeated use of the same chemistries, without the rotation of different herbicides or other methods of weed control.
Farmers experience mind-boggling annual economic losses due to weeds overtaking healthy crops.
Consumers are pushing for more natural products to be used on the foods they consume.
Governments increasing pressure to move toward natural products.
Harpe’s biological herbicides control weeds, including those with resistance to today’s synthetic chemistries, by harnessing nature’s unique combination of ingredients. Our groundbreaking technologies use a series of novel plant extracts to provide superior natural crop protection. The series of plant extracts serve as a platform that can be adjusted to fit different weed control scenarios.
Harpe enters the seedlings, interrupts the natural growth-signaling process, resulting in inhibition of weed-seed development.
*Controlled laboratory setting.
Harpe enters the plant cells through the cell wall, and disrupts membrane function by releasing large amounts of free radicals, peroxides, and ions into the cytoplasm. This results in discoloration of plant tissues, rapid wilting due to loss of turgor pressure, and, ultimately, rapid cell death.
As a new environmental and sustainable approach to weed control, Harpe’s platform of herbicides can be used alone or in combination with any currently available herbicide. The addition of Harpe’s new modes & sites of action will enhance synthetic herbicide efficacy – including control of resistant weed populations. The additive effect will reduce current synthetic herbicide amounts needed to achieve weed control
Technologies have been demonstrated as a natural partner in the battle against weeds and weed resistance. Harpe supports economic turnaround for farmers by maintaining the security of crops, while promoting benefits to the environment and the consumer.
By focusing on the use of compounds provided by nature and refining them to achieve broad-spectrum weed control naturally, Harpe herbicides are free from synthetic chemicals. The environmentally safe and sustainable approach to weed control meets the needs of all stakeholders.
Discovery platform taps into the power of plant extracts to commercialize natural herbicides to improve weed control. These ingredients are recognized as safe with positive safety profiles. Regulatory approvals can be expedited, time to market accelerated and targeted reduction in synthetic chemistry applications achieved.
The use of plant extracts provides an all-natural solution to weed control at a time when synthetic products are under increasing scrutiny with intense restrictions and market removal. Synthetic herbicides are becoming less user-friendly and less available to farmers. Harpe’s platform of herbicides are effective, safe, and easy for farmers to use.
The increase in demand for organic produce by consumers continues to surge. However, unlike in conventional farming, options available to control weeds in organic production remain limited at best. As all-natural products, Harpe’s herbicides will be submitted for OMRI certification assuring Harpe products are suitability and meet the conditions for certified organic production.
In Greek mythology, the harpe sword or sickle was used by Perseus to behead Medusa. Look closely at Medusa’s pernicious hair—and think pigweed. Field trials show that Harpe bioherbicide provides effective weed kill, not only for pigweed, but for a wide spectrum of weeds, including resistant biotypes, and other weeds that interfere with healthy crops.
