Know Your Pests When Trapping Soybean Looper in the Florida Panhandle

Ethan Carter, Tyler Shaw, Libbie Johnson, and Silvana V. Paula-Moraes

Pheromone trapping is a common scouting method used in collaboration with integrated pest management. A major crop pest of many plant species, including Panhandle crops like peanut and cotton, is the soybean looper.  A soybean looper pheromone-trapping study performed in Panhandle commercial peanut and cotton fields also attracted other species with similar appearances, sometimes in high numbers. Misidentification would result in overestimation of soybean looper populations and likely unnecessary insecticide applications. The sharp stigma looper, due to its high seasonal abundance and flight pattern similar to that of the soybean looper, was most concerning. This insect is not a pest and can be discerned from the soybean looper easily through its wing markings, if someone knows what to look for, but if these harmless moths were unwittingly thought of as soybean loopers, it could greatly skew population numbers and prompt improper applications of pesticides.

Insect and Mite Pest Management in Florida Peanut

Isaac L. Esquivel, Xavier Martini, Ethan Carter, and Silvana Paula-Moraes

Peanut is one of the most important cash crops grown in the United States, with an estimated production value of over $1 billion. The southeastern coastal plains harbor most of the US peanut acreage, and Florida is ranked among the top five major peanut producers in the US, with 160 thousand acres planted in 2022 and an annual production value of $130 million in 2021. The majority of peanut acreage in Florida is in the Panhandle and central Florida, in Jackson, Santa Rosa, and Levy counties. Several insect pests feed on various peanut plant parts, including foliage, roots, and fruiting structures. These pests can cause significant damage to the plant canopy and kernels and can also transmit diseases, reducing the quality and quantity of yield if they are not properly detected and managed. This publication serves as a guide for Extension agents and growers to provide an overview of proper sampling techniques and management for peanut pests found in the Florida Panhandle.

How to Obtain an Aldicarb Application Permit for Florida Cotton or Peanut

Zane J. Grabau, Ethan Carter, Libbie Johnson, Jay Ferrell, Dale Dubberly, and Tamara James

This publication is intended to guide growers through the process of applying for a free permit to use aldicarb, an insecticide/nematicide subject to particular restrictions because of its highly toxic nature and concerns about groundwater contamination when it is improperly applied. Aldicarb is currently labeled only for cotton and peanut in Florida. It is a restricted-use pesticide; thus applicators must have a current and valid private or commercial Florida pesticide applicator’s license with a row crop category designation and must obtain an aldicarb permit from Florida’s Department of Agriculture and Consumer Services before applying this product in Florida. This publication provides a guide to the permit application process for aldicarb.
