Tarnished Plant Bugs More Common Than Normal

By Phillip Roberts

Unlike cotton production areas in the Mid-South, tarnished plant bug is an uncommon and sporadic pest of Georgia cotton.  However, tarnished plant bug populations have been higher than normal and more insecticide applications have targeted tarnished plant bugs than usual during 2014.  Recently we have received reports of immature tarnished plant bugs in some fields; this is rarely observed in Georgia cotton.

Our primary method for scouting plant bugs is square retention.  Our goal is to retain 80 percent of all first positions as we enter bloom.  The square retention technique works well in pre-bloom cotton but is not as a reliable technique in blooming cotton as physiological shed confounds counts.

More scouts are using sweep nets to monitor plant bugs.  Sweep nets are an excellent tool for monitoring adult plant bug populations, but the drop cloth (especially a black drop cloth) is more effective for monitoring immature plant bugs.

Effective use of the sweep net becomes difficult after bloom due in part to plant size and more emphasis should be placed on use of a drop cloth.  Also be observant for both adult and immature plant bugs when making visual plant inspections; examine terminals and inside the bracts of squares, blooms, and small bolls.  Also be observant for “dirty blooms”, blooms in which many of the anthers are dried and brown.  Dirty blooms are an indication that plant bug (especially nymphs) are feeding on larger squares which the plant did not shed.

We do not have recommended thresholds for use of drop cloths, visual inspections, or sweep nets in Georgia.  However, entomologist in the Mid-South have developed solid workable thresholds when using these sampling techniques which should be applicable to Georgia cotton.

The FCDC and AgSmart Bring Plant Breeding to a Wider Audience

Video: The FCDC and AgSmart Bring Plant Breeding to a Wider Audience

In the vast prairies of Alberta, Olds College’s Field Crop Development Centre (FCDC) stands as a beacon of innovation and research in the agricultural world. The institution has become a key player in advancing agricultural technologies and practices. The FCDC’s commitment to applied research has driven them to seek effective means of disseminating their findings and creating a positive impact on the farming community.

One such avenue that aligns with their mission is AgSmart, an event dedicated to showcasing cutting-edge agricultural technologies. The coming together of the FCDC’s annual Field Day and Ag Smart has proved to be a natural fit, fostering a synergy that benefits both parties and propels the agriculture industry forward. The FCDC Field Day took part in conjunction with AgSmart for the first time this week on Aug. 1-2 in Olds, Alta. FCDC Program Director Kofi Agblor and Olds College VP of Development Todd Ormann sat down for an interview with Marc Zienkiewicz to discuss the significance of the two events taking part together and what the future holds.

The Intersection of Research and Technology The essence of the FCDC lies in its dedication to plant breeding and new seed varieties, particularly barley and triticale. While conducting research is essential, it becomes meaningful when its benefits are shared with the wider community. This is where AgSmart steps in, providing a key venue for the FCDC to showcase their research. This union between research and technology creates a holistic and enriching experience for farmers, ranchers, and industry professionals, the pair said.

Seeds as Technology For the FCDC, the partnership with AgSmart goes beyond mere event collaboration. It is about creating an environment that bridges the gap between seeds and smart technology, Ormann said. The college believes that for technology to truly revolutionize agriculture, it must begin with a strong foundation — high-quality seeds. As the saying goes, “it all starts with a seed.” To demonstrate this critical aspect, the collaboration aims to showcase the seed value chain as an integral part of the smartphone.

The Birth of a Powerful Alliance The idea of joining forces emerged when staff realized the potential synergy between AgSmart and the FCDC Field Day. With just a few days separating the two events, a proposal was put forward to merge them. The marketing and communications teams from both sides worked seamlessly to ensure the essence of both events remained intact, creating a powerful alliance that leverages the strengths of each, Agblor said.

Driving Advancements in Breeding For Agblor, the partnership with AgSmart has tremendous potential to drive advancements in breeding and other technology. With technologies like drones and imaging becoming integral to phenotyping, breeding is no longer confined to vast fields to assess thousands of plants manually. Instead, it benefits from the data-rich insights brought about by smart technologies. These advancements make breeding more efficient, precise, and instrumental in shaping the future of agriculture.

Overcoming Challenges Together While the partnership between Olds College and Ag Smart has been a resounding success, there are challenges on the horizon. Securing stable funding for long-term breeding initiatives is crucial to sustain progress. The college is committed to navigating these challenges and investing in agriculture’s future sustainably, Agblor said.
