Tackling pests and disease in an environment that’s anything but uniform

April 23, 2019

Readers of this month’s edition of The Grower, the technical journal for horticulture published by the AHDB might recognise a familiar image: the pointed microclimate sensor from 30MHz. In a contributed article, Ant Surrage, Technical Development Specialist at Fargro, goes in depth on the importance of quality data when crafting an integrated pest management (IPM) programme.

Growers, consultants and researchers in the 30MHz community have been demonstrating the impact of data-driven IPM, and we’re excited to see our technology be a part of their fight against pest and disease. Ant’s article highlights the key reasons why real-time insights are central to protecting crops from threats. At the core is a reminder to agribusinesses to never underestimate the variations in their environment.

“Growers must recognise that it is likely their environment is not uniform. Hotspots, areas of high humidity and areas of damp will be key areas for pest and disease establishment. This should inform monitoring and preventative programmes, which will have knock-on effects on other elements of an integrated pest management (IPM) programme.”

A combination of metrics on environment and crop-level insights (including dew point, vapour pressure deficit/VPD, absolute humidity/AH, humidity deficit and the absolute difference between air temperature and dewpoint) are all viewable within the ZENSIE platform, and provide the detailed overview needed to fight the range of insects, fungi and diseases that can compromise crop development.

“For even greater detail, growers can monitor and understand the microclimate. The microclimate refers to the environment around a plant, this is often significantly different to the environment we feel when walking through the crop. It is necessary to understand the microclimate.”

Real-time and historical data on environment and microclimate can help agribusinesses identify the conditions that lead to disease development, and optimise the conditions for biopesticide effectivity– a win-win that conserves crops as well as resources.

How can smart sensing transform your industry?
Sensory data from physical environments is helping businesses across industries make better decisions, improving productivity and cutting costs. Let's talk about how smart sensing can work for your organization. Get in touch below.

Integrating the human element with manual input

Data is always most powerful when it’s combined from a variety of sources. The more context you have available to you, the more informed your decision-making. Well documented, easy to explore information is always an asset, whether it’s validating tried and tested methods, providing extra support to a hunch, or creating the space for an ...

A clearer, objective picture: Madestein’s Jonathan Zwinkels on integrating climate control with 30MHz

Since it was founded by two husband and wife teams in 1982, Madestein UK has earned its reputation as a leading supplier of Leafy Salads and Herbs across the United Kingdom. The company currently focuses on growing whole head lettuce (round lettuce, curly leaf lettuce, red butterhead lettuce) and fresh basil and the propagation of ...

Why growers measure oxygen in the root zone

In addition to regular climate data from wireless sensors and climate computers, growers can now also see the oxygen level, pH value and temperature of the root environment in ZENSIE. Recently, 30MHz partnered with Sendot Research whose sensors can be connected to the data platform. In addition to oxygen and pH, Sendot also offers a ...
