“…Flumioxazin, a WSSA Group 14 herbicide, is registered for PRE use in watermelon and cantaloupe in Indiana with a Special Local Needs label as authorized under §24(c) of the Federal Insecticide, Fungicide, and Rodenticide Act. However, flumioxazin broadcast-applied over the top of polyethylene can cause watermelon yield loss (Meyers et al 2021), probably because it slowly dissipates from the polyethylene mulch (Grey et al 2009), thus increasing the chance of the herbicide contacting the crop and causing damage. Specialty crop farmers in Indiana prefer to spray over the top of plastic due to lack of hooded spray equipment.…”

Dose-response trials to determine the tolerance of summer squash and watermelon to fomesafen pre-transplant (over-the-top of black polyethylene mulch and respective row middles) were performed between 2020 and 2021 at three Indiana locations: the Meigs Horticulture Research Farm (MEIGS), the Pinney Purdue Agricultural Center (PPAC), and the Southwest Purdue Agricultural Center (SWPAC). Summer squash trials were performed at MEIGS and PPAC and watermelon trials were performed at MEIGS and SWPAC. The experiments for both summer squash and watermelon had a split-plot arrangement in which the main plot was herbicide rate, and the subplot was cultivar. Summer squash injury included necrotic leaf margin, chlorosis, brown and white spots, and stunting. Fomesafen rates from 262 to 1,048 g ai ha-1 in 2020 at both locations and from 280 to 1,120 g ai ha-1 in 2021 at MEIGS did not affect summer squash yield. However, in 2021 at PPAC, rates from 280 to 1,120 g ha-1 delayed summer squash harvest and decreased marketable yield from 95 to 61% of the non-treated control. Watermelon injury included bronzing and stunting. Fomesafen rates from 210 to 840 g ai ha-1 did not affect marketable watermelon yield and fruit number. Crop safety was attributed to rain washing off most of the herbicide from the polyethylene mulch before transplanting or to little to no rain after transplanting. Inury was only observed when there was no rain before transplanting followed by excessive rain shortly after transplanting. Overall, the 1x rates used for each trial were safe for use 1 d before transplanting summer squash and 6 to 7 d before transplanting watermelon.

About 90% of the Texas High Plains area depends on the water supply from the Ogallala aquifer. The decline of the Ogallala water table raises a concern for the sustainability of producing the traditional irrigated field crops due to their high water demand. Thus, diversifying cropping systems may be a solution. However, about 70% of the irrigated cropland uses center pivots that may negatively impact specialty crop quality. Thus, a 3‐year experiment was conducted to assess the potential of using mobile drip irrigation (MDI) to produce fresh watermelon compared to center pivot sprinkler irrigation using low‐elevation spray application (LESA), and surface drip irrigation with plastic mulch (DI). The study evaluated the effects of irrigation systems on crop yield, fruit quality, physiological responses, water use efficiency (WUE), and irrigation use efficiency (IUE). On average, plants under MDI had higher yields (106 Mg ha−1) than those under DI (70 Mg ha−1) and LESA (68 Mg ha−1). Plants under MDI and DI also had more fruits per plant (1.9) than those under LESA (1.4). The higher yield was associated with higher biomass and photosynthetic function. In general, fruit quality was not affected by irrigation system. In addition, plants under MDI system showed a higher WUE and IUE, and less water stress than those under LESA and DI systems. Results of this study suggest that irrigating under an MDI system is a good alternative for growers in the Texas High Plains that aim to diversify their cropping system with high‐value vegetable crops such as watermelon (Citrullus lanatus).
