Millipedes and Centipedes
Millipedes and centipedes do not carry diseases that affect people, animals or plants. Millipedes do occasionally damage seedlings by feeding on stems and leaves, and may enter homes in large numbers during periods of migration and become a considerable nuisance. They do not cause damage inside the home, although they may leave a stain if they are crushed. Centipedes, which have poison glands and can bite, pose an occasional threat to humans.

Bacterial diseases are among the major production and economic challenges that onion growers face in Georgia. There are six bacterial diseases that commonly affect onion foliage and bulbs in the state. These diseases are difficult to manage and rely mainly on cultural practices and the use of protective bactericides. Host resistance is limited with little information on pathogen biology and the infection process. This bulletin provides a comprehensive outlook on specific symptoms associated with bacterial diseases, modes of infection and spread, and potential management options.

La bermuda es una planta perenne de estación cálida ampliamente utilizada para su uso como césped en el sudeste de los Estados Unidos.
[Although improved common (Cynodon dactylon (L.) Pers.) and hybrid bermudagrasses (Cynodon dactylon x C. transvaalensis Burtt-Davy) have desirable qualities as turfgrasses for heat, drought and wear tolerance, bermudagrass is a problematic weed when grown in mixed stands with other turf species. Selective control of bermudagrass is difficult but often warranted in order to maintain acceptable quality of the desired turfgrass species. This publication describes bermudagrass control methods for Southern lawns.]

Aflatoxin is a naturally occurring toxin produced by the fungus Aspergillus flavus. The fungus can be recognized by a gray-green or yellow-green mold growing on corn kernels in the field or in storage. Plant stress due to drought, heat or insect damage during fungus growth usually increases aflatoxin levels. Aflatoxin contamination will reduce feeding value and hinder sales. Because it is extremely poisonous to warm-blooded animals even at relatively low levels, grain handling facilities often check for the presence of the toxin before purchasing corn.

La lespedeza común (Kummerowia striata (Thunb.) Schind syn. Lespedeza striata) es una leguminosa anual de verano sin organización en sus ramificaciones, que es una maleza problemática en céspedes de jardines residenciales así como en otras áreas de césped.
[Common lespedeza (Kummerowia striata (Thunb.) Schind syn. Lespedeza striata) is a freely branched, summer annual legume that is a problematic weed in lawns and other turf areas. This publication describes ways to identify and control Lespedeza in turfgrass, including cultural control methods, preemergence herbicides and postemergence herbicides.]

Watermelon production faces many challenges in Georgia. The warm, humid climate favors numerous foliar diseases. Because of the long history of watermelon production in Georgia, soilborne diseases such as Fusarium wilt also present challenges to growers. This bulletin will provide background on disease symptoms, pathogen survival and infection, pathogenic races, and management.

This integrated pest management (IPM) guide for blackberry and raspberry production includes management of diseases, insects, and weeds through IPM principles. The 2024 Southeast Regional Caneberry Integrated Management Guide covers topics such as pesticide stewardship and safety, insect and disease control, pre-transplant and transplant operations, fungicides and insecticide efficacy comparisons and spray schedules, weed management, wildlife damage, and more. Recommendations are based on information from the manufacturer’s label and performance data from research and extension field tests. Because environmental conditions and grower application methods vary widely, suggested use does not imply that performance of the pesticide will always conform to the safety and pest control standards indicated by experimental data. This publication is intended for use only as a guide. Specific rates and application methods are on the pesticide label, and these are subject to change at any time.
