“…The effect of soil surfactants on water properties and pesticide movement has been investigated with varying results. Mobbs et al (2012) reported anionic, nonionic, and block polymer surfactants did not affect infiltration rates and water holding capacity of a silt loam and sand soil; however, significant differences were reported for hydraulic conductivity and capillary rise in sand soil only. Revolution is a nonionic modified methyl capped block co‐polymer and was included as the soil surfactant within this research due to anecdotal evidence suggesting it may enhance abamectin efficacy (Zontek and Kostka, 2012).…”

“…Aamlid et al (2009) reported Revolution reduced leaching of fungicides with greater aqueous solubility including azoxystrobin and propiconazole in sand‐based putting greens compared with no soil surfactant inclusion; however, Revolution did not enhance abamectin distribution within this research compared with abamectin fb irrigation or irrigation fb abamectin fb irrigation at 7 or 28 DALT, which may be due solely to very low aqueous solubility of abamectin. Mobbs et al (2012) noted tested surfactants did not perform consistently across a series of experiments, indicating inherent variability with soil surfactants and also reported single applications did not affect water movement in evaluated soils. Larsbo et al (2008) evaluated the effect of a nonionic soil surfactant (Primer 604 ® ) on fungicide leaching from golf course putting greens and reported increased water infiltration rates and reduced azoxystrobin, iprodione, and propiconazole leaching.…”

Irrigation and Soil Surfactants Affect Abamectin Distribution in Soil

Nematodes are microscopic, soil‐dwelling organisms that adversely affect many turfgrass systems, including golf course putting greens. Abamectin controls many nematode species in golf course putting greens; however, high sorption to accumulated organic matter near the soil surface in established turfgrass systems may limit its distribution in soil, thereby limiting its efficacy. Field research was conducted on ‘A1/A4’ creeping bentgrass and ‘Champion’ ultradwarf bermudagrass putting greens to evaluate abamectin distribution in soil following treatment regimens including abamectin application (37 g a.i. ha–1) alone, or tank‐mixed with soil surfactant (Revolution) in tandem with various irrigation timings to promote downward distribution. Laboratory research was also conducted to evaluate 14C‐abamectin soil distribution via treatments comprised of various combinations of simulated irrigation amounts and timings, as well as soil surfactant type (Dispatch or Qualibra) and timing with respect to abamectin application. Abamectin distributed similarly in soil across turfgrass species in field research. At 7 d after treatment (DAT), all irrigation–soil surfactant regimens increased abamectin distribution to the 0‐ to 2.5‐cm soil depth compared with broadcast spray alone; however, no evaluated regimen resulted in >2% of the applied abamectin movement beyond 2.5 cm. In laboratory experiments, 14C‐abamectin soil distribution was affected most by soil surfactant at 3 DAT, with Qualibra increasing distribution (8.2 to 18.4% of applied) to 7.5 cm depth compared with Dispatch or no surfactant. As in field research, irrigation amounts and timings generally affected 14C‐abamectin similarly. This research highlights practices to enhance distribution into the profile, thereby increasing bioavailability and efficacy.

“…), colza (Brassica napus L.) and linum (Linum usitatissimum L.) are used as test plant, a significant difference has not occurred in the condition that nonionic surfactants (Triton XA, Wex and Renex 36) are added to herbicide tanks. It is understood from the previous study results that the yield of potato is not affected with nonionic surfactant addition but N amount of plant increases [29], singlet applied anionic, nonionic and block polymer surfactants do not develop the protection and movement of soil water in hydrophilic soils [30], in the greenhouse conditions the application of 1000 mg kg -1 level nonionic surfactant to oaten, trefoil and pea causes plant growing to regress [31], the application of 6.000 and 12.000 mg kg -1 level surfactants to the soil taken from 300 g SL structured Ap horizon affects barley growing negatively [32]. Thus, positive impacts on plant growing do not appear in these conditions.…”

Surfactant is used as wetting agent, dispersant, emulsifier, foaming agent, bactericide in detergent, soap, herbicide and insecticides.The pollution from their residue in nature affects agricultural products as well. In this study was performed to determine the effects of anionic, cationic and nonionic surfactants on the dry weight of wheat (Triticum aestivum). This research was conducted as randomized split parcels with 3 repetetives in greenhouse. Surfactants were applied at 0, 180, 360, 540 and 720 mg kg -1 concentration after sowing, it was harvested on the 50 th day. Anionic surfactant caused to decrease the dry weight (p < 0.05) of wheat plant. While cationic surfactant caused to decrease the dry weight (p < 0.05), the application of nonionic surfactant did not.According to study results; anionic and cationic surfactants have a negative impact on the growth of plant roots of wheat. Therefore experiencing difficulties in the acquisition of plant nutrients can be attributed to a decrease in plant dry weight.

Influence of Gypsum and Wetting Agent on Sand‐Based Putting Greens Irrigated with Recycled Wastewater

Recycled wastewater (RW) is a source of irrigation for golf courses in many parts of the world. The objectives of this study were to determine the effects of gypsum and wetting agent applications on the turfgrass quality, clipping yield, root zone chemical and physical properties, and leachate of a sand‐based putting green irrigated with secondary and tertiary RW. Our results showed that gypsum amendment produced better turfgrass quality under summer heat stress than the wetting agent and the control. Soil water infiltration was impeded by secondary and tertiary RW but was improved by the gypsum treatments. When compared with topdressing with straight sand, the wetting agent application did not improve turfgrass quality or soil properties when irrigated with RW. Monthly applications of a wetting agent resulted in lower water infiltration rates, but the values remained within the U.S. Golf Association recommendations for putting green construction. Golf course superintendents are encouraged to use gypsum when managing sand‐based putting greens with RW as the primary source of irrigation water.
