Below you'll see everything we could locate for your search of “weeds”
Ajia Paolillo and Ramdas Kanissery with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) wrote in an Extension newsletter about clustered pellitory, a recently established weed in citrus groves. Paolillo is a multi-county citrus Extension agent. Kanissery is an assistant professor specializing in weed science. Clustered pellitory is native to Florida and other areas in the southeastern …
Summer is “a field day for weeds,” Ramdas Kanissery said in a March 29 presentation about weed control for citrus. The University of Florida Institute of Food and Agricultural Sciences assistant professor provided a progressive step-by-step approach to suppressing weeds during the summer. CONTROL EXISTING WEEDSGrowers can get off to a good start by controlling existing weeds with post-emergent herbicides. …
By Danielle Leal Over the years, new weeds have surfaced, and old weeds have developed resistance and become tougher to control. Crop scientists are currently researching ways to successfully manage weeds in citrus. Sonia Rios, technical development representative for Bayer Crop Science, said growers are heavily dependent on post-herbicides to help mitigate weeds. “In order to use a pre-herbicide, you …
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 …
There are many advantages to using cover crops in citrus groves, according to Sarah Strauss, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor. She recently discussed growers implementing cover crops at the Citrus Health Forum at the UF/IFAS North Florida Research and Education Center in Quincy. “Certainly, from the microbiology side, the scientific side, I think …
By Ramdas Kanissery The use of compost in tree rows is receiving increasing attention among citrus growers. The use of weed-free certified products can considerably minimize the weed emergence issues associated with compost use. However, eventually, weeds will start to grow in the composted areas in the grove. As compost and similar soil amendments prove to be very rich in …
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 …
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 …
Nearly every Florida citrus grower will sooner or later experience aquatic weed control problems. Aquatic plants are necessary for maintaining the balance of nature and offering food, protection, oxygen and shelter to aquatic species. However, maintaining a balance in the aquatic system while sustaining crop success and avoiding loss of income can be a challenge. Excessive aquatic weed growth can …
By Ramdas Kanissery and Mongi Zekri Newly planted citrus trees and resets require more care and attention than established trees, especially when it comes to weed control. Florida’s weather conditions like high summer temperatures and often heavy rainfall make weed control in young groves difficult. Weeds compete with young citrus trees for nutrients, moisture and other resources, and may hinder …
(UF/IFAS) — The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Extension bookstore has released an updated version of “Identification of Weeds in Florida Citrus,” a pocket-sized quick reference guide to weeds commonly observed throughout the state that may be frequently found in citrus groves. “The comprehensiveness of this guide makes it useful not only for growers in …
Like many farmers nationwide, citrus growers are looking for any edge in their fight against weeds, and they’d rather use fewer chemicals to control the plants, says a University of Florida scientist. That’s because chemicals can get into groundwater, surface water and plants themselves. Weed scientist Ramdas Kanissery and his colleagues at the University of Florida Institute of Food 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 …
At the Florida Citrus Growers’ Institute on April 2, weed scientist Ramdas Kanissery explained how growers can control weeds with a combination of early management, herbicides and steam. His talk was one of several presentations University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers made to an audience of more than 200 citrus growers in Avon Park. Kanissery, …
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 …
By Mongi Zekri 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. The fate processes for pesticides fall into three major types: adsorption, transfer and degradation. PESTICIDE ADSORPTION The adsorption process binds …
Cold-hardy citrus growers are on the cusp of starting another harvest season. Management options need to continue up until the first crops are plucked from the trees, according to Certified Crop Adviser Bill Barber with Ag Services LLC. Barber spoke at a citrus workshop on Sept. 24 at the University of Florida Institute of Food and Agricultural Sciences Extension office …
Organic citrus growing presents unique hurdles in Florida, Texas and other southern states. Poor soil quality, nutrient deficiencies and a limited range of pest control options plague organic production. But the University of Florida Institute of Food and Agricultural Sciences’ (UF/IFAS) Davie Kadyampakeni is poised to transform the future of organic citrus growing. He aims to do that with a …
Two University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers and an Extension agent authored an article in the Cold Hardy Citrus Connection about the invasive peanut snail in citrus. The authors are Xavier Martini, associate professor of entomology; Issac Esquivel, assistant professor of entomology; and Extension agent Danielle Williams. Excerpts follow. Bulimulus bonariensis (also known as Bulimulus …
By Ramdas Kanissery Managing weeds during the summer is crucial for Florida citrus. However, due to the high temperatures typical of Florida’s summer months, several factors must be considered when using herbicides in citrus groves during hot weather. INCREASE EFFECTIVENESS High heat and drought stress can slow plant growth and affect how herbicides move or translocate in weeds. When temperatures …
