Aphids, Bollworms, Stink Bugs, and Tarnished Plant Bugs Complicating Insecticide Management

By Dominic Reisig 
 
Well it is definitely mid-season cotton management time here in North Carolina. Lots of questions on a complex of insect pests present in the Coastal Plain. Bollworm flight activity has picked up on cue (link to light trap information) and any management decisions made for other pests should also revolve around this pest. To avoid flaring bollworm and other pests, it is critical that we maintain as many natural enemies as possible. This can be accomplished by using more selective insecticides and avoiding broad spectrum insecticides unless they are needed. As a rule of thumb, carbamates (e.g., Vydate) and organophosphates (e.g., Bidrin, Lorsban, Orthene) are the harshest on natural enemies, followed by pyrethroids (e.g., bifenthrin, Karate/Warrior). 
 
Aphids have been widespread and problematic. Generally they are held back by natural enemies and a fungus, but we haven’t yet spotted fungal activity in our state (generally associated with warm and moist conditions). Aphids can be a problem if cotton is stressed and especially when it is planted late. We can hold off on a dedicated aphid spray unless they are clearly stressing the cotton. Transform is a good choice for aphid control since many populations in our state are resistant to neonicotinoids (e.g., Admire, Belay, Centric). It also has the added advantage of preserving most natural enemies and is the product of choice during a bollworm flight.
 
Stink bugs have been heavy in both Georgia and South Carolina, but are one pest complex that we should be able to stay on top of. Bifenthrin or Bidrin are effective for brown stink bugs and pyrethroids, in general, are good for greens. As stated in the first paragraph, avoid Bidrin or Orthene during bollworm flights unless a major cleanup is needed or if you are prepared to spray Prevathon or Besiege in Bollgard II, TwinkLink, or WideStrike varieties.
 
Tarnished plant bugs are still around in some spots and should be considered when insecticide applications are made. Transform is a good choice during bollworm flights because natural enemies will help hold them back. If tarnished plant bug pressure is heavy, pyrethroids + Orthene might be needed in severe cases.

Why Rob Saik is Trying to Build the World’s Most Connected Agriculture Network

Video: Why Rob Saik is Trying to Build the World’s Most Connected Agriculture Network

In a recent interview at the SeedLink Conference in Brandon, Man., Rob Saik, author, speaker, and CEO of AGvisorPRO, took a trip down memory lane, reminiscing about the beginnings of his career and what the future holds.

Graduating from the University of Alberta in 1983, Saik embarked on a journey that started in Brandon, Man. “I got a job with Elanko, got a U-Haul truck, threw everything I had into it, drove to the Victoria Inn, and lived there for three months while they tried to find an apartment for me to move into. So I started my career in Brandon,” Saik shared.

Fast forward to the present, Saik has evolved into an accomplished author and speaker, traversing the globe to engage in high-level discussions about the future of agriculture and the critical role it plays in feeding the world. Yet, despite his global presence, he finds himself back in Brandon, addressing a group of seed growers. But why? Saik emphasizes the fundamental importance of seeds, stating, “It all begins with a seed, doesn’t it?”

Reflecting on his own experiences as a farmer, Saik expresses his excitement when a planted seed germinates and evolves into a thriving crop. He underscores the significance of technology and breeding in seed development, recognizing the crucial role they play in ensuring farmers can propagate seeds, grow profitable crops, and contribute to global food security.

Saik delves into the challenges faced by the agricultural community, particularly the rapid pace of technological advancements. He believes that the key lies in connecting farmers to experts swiftly, boosting farmers’ confidence in adopting new technologies, and ensuring the timely implementation of these advancements. According to Saik, this approach is crucial for steering agriculture towards sustainability and profitability.

As Saik works on his upcoming book, tentatively titled prAGmatic, he sheds light on its central theme. “The thesis would be that I want to write a book that takes what the consumer wants, challenges what the consumer believes, and positions that against what the farmers can actually do pragmatically,” he explains. The book aims to bridge the gap between consumer expectations and the realistic capabilities of farmers, promoting sustainable intensification as the necessary path to feed the planet.

Looking ahead to 2024, Saik emphasizes the need for enhanced connectivity within the seed industry. He discusses his platform, AgvisorPro, which is designed to facilitate connections between farmers, experts, and companies in a way that transcends conventional social media platforms. Saik envisions a credible, connected agricultural network that goes beyond the noise of platforms like LinkedIn or Twitter.

In a passionate vision for the future, Saik imagines a tool for teachers that allows them to pose questions from students, answered by verified farmers and ranchers. This, he believes, would provide an authentic and valuable educational resource, connecting classrooms with individuals who truly understand the intricacies of agriculture.
