Chrysomelid leaf beetles and pentatomid stink bugs often use male-produced aggregation pheromones (attractive to males and females) to colonize hosts, including crops. Some important pests’ aggregation pheromones are already known and synthesized. Availability of synthetic pheromones offers opportunities to develop behavioral control as an important tactic in vegetable IPM, while ...

In California, nearly 95% of the population lives in urban or suburban areas. It is inevitable that they will encounter pests, especially those of public health significance such as cockroaches, rats, bed bugs, and mosquitoes, some of which may also be considered invasive. It is also likely that many will ...

Fungicide applications are a common integrated pest management (IPM) tool, yet their use often follows a set schedule or crop stage rather than actual need. Overuse can drive fungicide resistance, undermining long-term effectiveness. The occurrence of plant disease requires a susceptible host, a pathogen, and favorable environmental conditions. Thus, fungicides ...

Onion downy mildew, caused by the oomycete Peronospora destructor, is a highly destructive foliar disease of onion. The disease does not occur every year in the Holland Marsh, Ontario, Canada, so disease forecasting can be very useful. Symptoms develop 10 – 14 days after infection and downy mildew specific fungicides ...

When it comes to crop management, we want to give our soybeans the maximum amount of time possible in the spring to develop leaves and nodes. This way the plant will be able to support high yield from flowering all the way to harvest.

In our study of over 100 different growing environments across 22 states, none of the biostimulant products evaluated increased soybean yield compared to the non-treated control. This fact sheet explains the project and results.

Stemphylium leaf blight (SLB) caused by Stemphylium vesicarium is the most common foliar disease of onion in Ontario, Canada. Management of SLB relies on repeated fungicide applications and most fungicides are in the succinate dehydrogenase inhibitor (SDHI) mode of action group. The strobilurin fungicide, azoxystrobin was applied regularly until very ...

Understanding soybean water use is essential for effective irrigation management. By pairing this knowledge with a well-planned irrigation schedule or tool, farmers can optimize both water use efficiency and profitability.

Yield maps made using yield monitor data are very good at visually displaying relative yield differences in a field, but extra care must be taken if you want to use yield monitor data to estimate field average yields.

In this paper, we aim to explore the practical opportunities and implications of Climate-Smart Forestry (CSF) as a strategy for enhancing carbon offset initiatives, particularly in forested landscapes susceptible to climate change impacts. Our objectives include discussing how landowners can engage in CSF practices and programs, identifying eligible management practices ...

The objectives of this management guide are to (a) address the necessary considerations prior to replanting a soybean field; (b) provide images depicting common early season stressors affecting soybean; and (c) explain the potential yield limitations from early season soybean injuries

Improved crop management practices and genetics, coupled with a changing environment have led some farmers to shift their soybean planting dates earlier than the traditionally recommended planting dates. While planting time varies by geographic region in the US, most soybean farmers can do early planting without compromising yield potential by ...

Healthy corn leaf 3D model. Can be modified as needed.

This multi-color 3D model shows various lesion types on a soybean stem including Phytophthora, stem canker, pod and stem blight, and Rhizoctonia. This GCODE file is for Bambu Lab P1S printers.

Natural Enemies are beneficial organisms that provide biological control, or natural pest control. Many natural enemies are insects. This guide illustrates common natural enemies found in agricultural crops and home gardens. In addition to photos, we indicate key characters to identify each natural enemy.
