By Ramdas Kanissery It is essential to maintain a patch of weeds or vegetation in the row middles to hold the soil from eroding and, at the same time, without being a source for weed invasion into the tree rows (Figure 1). Below are some quick tips for managing the vegetation in row-middle spaces between the citrus tree rows: MOW …
By Ramdas Kanissery Weeds emerging in citrus rows are problematic as they compete for resources with the trees, support pests and interfere with grove operations like irrigation (Figure 1). Hence, effective strategies to control weed emergence should be in place. Pre-emergence (or residual) herbicides are an excellent tool for the long-term suppression of weeds in tree rows. These herbicides …
By Ramdas Kanissery, Nirmal Timilsina and Mongi Zekri Weed control is crucial for the growth and establishment of young citrus trees. Chemical weed control with herbicides is an efficient and cost-effective method for managing weeds in newly planted groves. However, before applying herbicide products, care must be taken to avoid damaging young trees and newly planted resets. Every so often, …
When developing a weed management program, there are many things for growers to consider. Application site, the stage of weed growth, herbicide selection, the amount of herbicide used, spray volume and pressure, and herbicide bandwidth are just a few of the factors that contribute to the cost and success of a weed management program. Ramdas Kanissery, weed scientist at the …
By Ramdas Kanissery Adjuvants (derived from Latin, adiuvare: to aid or help) are materials added into an herbicide spray solution that improve handling, performance and crop safety. To be effective, an herbicide must overcome certain environmental and biological obstacles before entering and acting in the weeds. For example, environmental conditions like hot and dry weather will result in a thicker …
Weeds can reduce citrus growth and production, especially in young trees. A management program should be put in place to control weeds in tree rows to minimize competition with citrus, but it is also important to control weeds in row middles to reduce soil erosion. Weed management can be achieved by utilizing a combination of control practices including but not …
By Ramdas Kanissery Citrus growers face weed management problems throughout the year due to favorable conditions that allow the rapid growth of weeds in groves. A weed-free tree row is desired in citrus to minimize competition with the trees. This can be achieved by utilizing post-emergent herbicides that control the weeds that have already emerged. Growers have several product options …
Protect Young Citrus from Grasses, Broadleaf Weeds & Nutsedge Weeds in citrus groves can cause yield loss of up to 33%, according to research published by the University of Florida (UF) Citrus Research & Education Center. This significant – yet largely preventable – level of yield loss can be due to weeds that interfere with harvesting, serve as alternate hosts …

Weed management is a key component of Florida’s citrus production. A warm, humid climate and frequent rainfall provide a favorable environment for weed emergence and growth in citrus groves. Steve Futch, a former multi-county citrus Extension agent for the University of Florida Institute of Food and Agricultural Sciences, delivered a presentation during the 2021 virtual Southeast Regional Fruit and Vegetable …
By Ramdas Kanissery Tank-mixing different herbicides with multiple selectivity and modes of action will broaden the range of weeds controlled in a single application. Although it is an effective and popular strategy, when components (herbicide products and spray additives) in the tank mixes are not compatible with each other, the resulting combination can produce unintended and unsuccessful results. THINK BEFORE …
By Ramdas Kanissery, Rachel Fenn, Biwek Gairhe and Davie Kadyampakeni Chemical weed control, using herbicides to manage weeds, is an important production practice in citrus groves. Herbicides applied in groves can end up in the soils from direct spray hits, indirect or non-target spray movement (also known as drifts) or release from the dead weeds and vegetation. In soil, the …
By Ramdas Kanissery, Miurel Brewer, Davie Kadyampakeni and Sarah Strauss Florida growers face problems with weeds throughout the year due to favorable weather conditions that allow rapid proliferation and lush growth of weeds in groves. While a weed-free tree row is desired to minimize competition with citrus, it is also essential to manage the weeds or vegetation in the row …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) weed scientist Ramdas Kanissery has earned a Dallas Townsend Extension Professional and Enhancement Award. Kanissery works at the Southwest Florida Research and Education Center (SWFREC) in Immokalee. “The award recognizes a state Extension specialist for demonstrating an outstanding ability to plan and implement Extension programs that address needs that have …
Citrus growers can get continuing education units (CEUs) from the 2020 Florida Citrus Growers’ Institute, even though the in-person version of the annual event was cancelled due to COVID-19. Multi-county citrus Extension agent Chris Oswalt discusses how growers and others can get their restricted-use pesticide license or Certified Crop Advisor CEUs. “We have started to receive those presentations from those …
A federal appeals court in New York has upheld the dismissal of a claim that Florida’s Natural Growers’ (FNG) use of the word “Natural” in its brand name was deceptive. The U.S. Court of Appeals for the Second Circuit made the ruling on May 29. The appeals court held that the company’s use of the word “Natural” in its …
Avoiding harmful effects of pesticides By Juanita Popenoe Editor’s note: This article grants one continuing education unit (CEU) in the Core category toward the renewal of a Florida Department of Agriculture and Consumer Services restricted-use pesticide license when the accompanying test is submitted and approved. Pesticides can have harmful effects on people, animals and the environment. The government tests and …
By Ramdas Kanissery, Camille McAvoy and Mongi Zekri Some weeds are more difficult to manage in the production system than others due to their ability to grow in an available niche. If given a chance to establish, Guinea grass and goatweed can be the two most difficult weeds to manage. This is not just because they both are prolific seed …
By Juanita Popenoe and Lauren Diepenbrock Ed James has citrus in his veins. He has been working and thriving in the citrus business since he was a teenager — from hoeing orange trees to owning a caretaking business that serviced thousands of acres. That is, until about eight years ago. In 2010, James looked around his personal 45-acre citrus grove …
By Ramdas Kanissery and Camille McAvoy Weedy vines are among the problematic and difficult to manage group of weeds in citrus. Vine weeds twine around the trees, competing with citrus for light and nutrients and causing reduction in yield and harvesting efficiency. Since vines do not have to form strong upright stems, more energy and resources can be diverted into …
