Abstract
Carrageenophytes such as Eucheuma and Kappaphycus play a vital role in supporting coastal economies and supplying the global hydrocolloid industry, with Indonesia producing over 75% of the world’s supply. However, the unregulated use of chemical liquid fertilisers (CLF) in seaweed farming poses serious ecological and socio-economic threats. In Sikka Regency, Indonesia, CLF use contributed to a decade-long collapse in cultivation, worsened by destructive fishing practices. Although efforts to revive farming began in 2018, current monitoring data are limited and fragmented. Nutrient over-enrichment from fertilisers has been linked to harmful algal blooms, epiphyte overgrowth, and diseases like ice-ice. While countries like the Philippines have introduced standards such as the GAqP for seaweeds, Indonesia still lacks formal regulation on fertiliser use. Misleading scientific claims and social media endorsements further promote detrimental practices. This article highlights the urgent need for public awareness, science-based guidelines, and coordinated policy to safeguard sustainable seaweed aquaculture. Extension services, farmer cooperatives, and social media can raise awareness, but added resources are required for guidelines, stronger policies, and market incentives discouraging CLF use.

Three water balance models were used to quantify water use efficiency on 71 golf courses in the United States. The golf courses were separated into five geographic regions. The United States Golf Association (USGA), Tipping‐Bucket (TB), and Agro‐IBIS (AG) water balance models were used to estimate golf course water requirements. Actual water use was divided by the water requirement from each model to generate three water efficiency scores for each golf course (WES USGA , WES TB , and WES AG ). The mean WES USGA was 1.16, the mean WES TB was 1.25, and the mean WES AG was 1.17. Thus, golf courses in this study used between 16% and 25% more water than predicted by the three models. The coefficients of variation of WES USGA , WES TB , and WES AG were all 0.45 or higher, indicating that some golf courses used significantly more or less water than predicted by the models. Rooting depth, irrigated area, and soil texture were especially important modeling parameters for the golf course water requirement calculations. While onsite evaluation should still be carried out to verify the assumptions made by the water balance models, the models are promising tools to quickly identify golf course superintendents who are likely to be using water efficiently and those who could use less.

The aim of this study was to determine insecticide efficacy for symphylan Scutigerella immaculata (Newport) control when establishing tall fescue grown for seed. Activated carbon is commonly sprayed over grass seed rows during establishment, followed by a broadcast application of nonselective herbicide where the carbon absorbs the herbicide and the grass germinates through the carbon layer. On April 24, 2024, a tall fescue (cv ‘Titanium GLS’) trial was planted in a symphylan-infested field at the Oregon State University’s Hyslop Research Laboratory near Corvallis, Oregon using a John Deere 5055 tractor and Sunflower 9312 drill seeder. The seeding rate was 11 lbs/acre and seeding depth 0.35 inch. Plot size was 30 ft × 16.3 ft with four replications of each insecticide treatment. During planting, activated carbon (OXPURE 325A-9, Puragen Activated Carbons, Palm Beach Gardens, FL) was applied directly over the seed row in a 1 to 1.5-inch band at 16.67 lbs/acre at 20-inch row spacing (300 lbs/acre broadcast rate). The insecticide treatments listed in Table were tank mixed with the activated carbon and applied during planting using a tractor-mounted sprayer calibrated to 50 gal/acre at 15 psi and equipped with Teejeet 8008 VA nozzles. Insecticide application was immediately followed by a broadcast application of Diuron 4L (diuron) herbicide at 2 lbs/acre AI for weed control. Treatments received 0.4 inches of rainfall and 0.5 inches of irrigation water within 24 hours of planting and treatment application. Above-ground percent crop cover data were collected from two randomly selected 4 ft × 1 ft quadrants within each plot by photographing the crop at 48 and 65 DAT (days after treatment). Mean percent crop cover data were analyzed using green canopy cover measurement in the 2024 Canopeo App and evaluated in SAS 9.4 using ANOVA and means separated using Fisher’s protected LSD (P ≤ 0.05) as shown in Table 1.

Abstract Timothy ( Phleum pratense L.) is a cool‐season perennial forage grass species widely utilized for animal feed and fodder in temperate regions of the world. Timothy is one of the main forage grass crops grown for seed in the Peace Region of western Canada. Timothy performs well under well‐fertilized and high‐moisture soils, but seed production fields are prone to lodging under such conditions. Lodging in grass crops reduces seed production through self‐shading, which limits successful pollination, fertilization, and seed fill. In this study, we investigated the effects of two plant growth regulators (PGRs), chlormequat chloride (CCC) and trinexapac‐ethyl (TE), on plant height, lodging, seed weight, and seed yield of timothy for 8 site‐years. The study encompassed 5 years at one site with crop stands in their first to fifth year of seed production and 3 years at a second site with crop stands in their first to third year of seed production. The PGRs were applied alone (TE and CCC) and in a mix (TE + CCC) at the 2–3 node (Biologische Bundesanstalt, Bundessortenamt, and Chemische Industrie [BBCH] 32–33) and early heading (BBCH 51–52) growth stages. The application of PGRs (TE, CCC, and their mix) at two different growth stages showed a differential decrease in lodging and plant height and an increase in seed yield in all but 1 site year. Among the PGR treatments, CCC applied at the BBCH 32–33 was the most effective in increasing seed yield and economic returns of timothy.
