As planting season begins across the West, Western Plant Health is reminding farmers about the importance of following basic steps that will help ensure the ongoing stewardship of pesticide-treated seeds, which help reduce the overall use of pesticides. This major agricultural advance provides seed treatments that help protect developing seeds during their most vulnerable time – at planting and germination. …

Tomatoes are big business in the United States, but an insect no bigger than a grain of rice threatens growers’ fields each season. The whitefly prefers the underside of leaves, enjoying a variety of plants and spreading a few diseases, including Tomato yellow leaf curl virus. The pests are also persistent, said Xavier Martini, an entomologist at the University of Florida Institute of Food …

The word ‘honeydew’ sounds benign, but the sugary waste product of aphids can promote growth of bacteria that are highly virulent to the pests, according to a new study. The research takes a step towards understanding how some strains of the bacteria Pseudomonas syringae that live on leaves and are pathogenic to aphids might one day be used to control …

While not exactly the stuff of sci-fi movies, scientists have developed a “ray gun” that emits a light hazardous to a pestilence that devastates many types of crops. Fumiomi Takeda, a research horticulturalist, and Wojciech Janisiewicz, retired research plant pathologist, from the Agricultural Research Service (ARS) Innovative Fruit Production, Improvement, and Protection unit in Kearneysville, WV, led a team that used shortwave ultraviolent …

USDA ARS — Adding cooked black beans to a high-fat diet improved sensitivity to insulin and other measures often related to diabetes and restored gut bacteria balance in obese mice, according to a USDA Agricultural Research Service study. As little as the mouse-size equivalent of a single serving a day of black beans—about a half cup for a human—lowered insulin …

Plants regulate their growth and development using hormones, including a group called strigolactones that prevent excessive budding and branching. For the first time, scientists led by UC Riverside have synthesized strigolactones from microbes. The work is published in the open-access journal, Science Advances. Strigolactones also help plant roots form symbiotic relationships with microorganisms that allow the plant to absorb nutrients from …

Grower-Shipper Association of Central California (GSA) — Implementing effective disease and pest management strategies is a continual challenge for farmers. While these challenges are not new in agriculture, they impact more than just farmers. Lower yields due to disease and pest pressure affects farm employees and harvesting crews too and can also inhibit our ability to provide a steady supply of affordable …

The dining time of different insects impacts a plant’s defenses and nutritional quality—a complexity uncovered in new research with implications for pest management strategies. A piercing-sucking, virus-carrying aphid has long worried pea plant farmers, but a more innocuous-seeming weevil that only takes tiny bites from leaves was found to also play a significant role in plant health. Depending if the …

The 2020 Agricultural Chemical Use Survey of vegetable producers collected data about pesticide use as well as pest management practices on acres planted to 22 different vegetable crops. NASS conducted the survey among producers in 18 states, focusing on the states that were major producers for the surveyed crops. (Fig. 1) Data are for the 2020 crop year, the one-year period …

The third edition of a booklet to help identify noxious and invasive weeds in New Mexico is now available. “Noxious and Troublesome Weeds of New Mexico” provides information on about 67 plant species that are ranked in five categories – noxious weeds categories A, B and C, watch list, and troublesome weeds not included on the noxious weeds list. New …
