“…Equations developed by Van Dyke and Anderson [ 18 ] and given below were used in the determination of relative forage value. Firstly digestible dry matter (DDM), secondly dry matter intake (DMI) was estimated and finally relative feed value (RFV) was predicted.…”

ObjectiveThis study was carried out to determine the effects of cumin essential oil on the silage fermentation, aerobic stability and in vitro digestibility of alfalfa silages.MethodsAlfalfa was harvested at early bloom (5th cutting) stage in October and wilted for about 3 hours. The research was carried out at three groups which were the control group where no additive control was done (CON), cumin essential oil (CMN3) with 300 mg/kg and CMN5 with 500 mg/kg cumin essential oil addition. Alfalfa was ensiled in plastic bags. The packages were stored at 8°C±2°C under laboratory conditions. All groups were sampled for physical, chemical and microbiological analysis 120th day after ensiling. At the end of the ensiling period, all silages were subjected to an aerobic stability test for 7 days. In addition, enzimatic solubility of organic matter (ESOM), metabolizable energy (ME), and relative feed value (RFV) of these silages were determined.ResultspH level decreased in the cumin groups compared to CON (p<0.05), thus inhibiting proteolytic enzymes from breaking down proteins into ammonia. In addition, it increased ESOM amount, and concordantly provided an increase of ME contents. Similarly, dry matter intake and RFV ratio increased. After opening the silage, it kept its aerobic stability for three days.ConclusionCumin essential oil improved fermentation, and affected chemical and microbiological characteristics of silages. Especially the addition of 300 mg/kg cumin provided cell wall fractionation through stimulating the activities of enzymes responsible. It also increased the number and activity of lactic acid bacteria (LAB) through providing a development of LAB.

“…However, dollar spot was less severe in year two of the study when nitrogen deficiency should have been more severe. In addition, recent research from Townsend et al (2020) indicted that there was no difference in dollar spot severity on creeping bentgrass fertilized with 0.0, 4.9, or 9.8 kg N ha −1 annually, and only minimal impacts when fertilized with 19.4 kg N ha −1 . It wasn't until 29.3 kg N ha −1 was applied that a significant decrease in dollar spot was observed.…”

“…In this same analysis, Civitas was rated as a 2 (defined as ‘fair to good control in most experiments’) for dollar spot control, while not enough information was available to provide a rating for Zio. In addition, disease suppression using Civitas has often been modest and applying in concert with synthetic fungicides is commonly required to achieve acceptable disease control (Clarke et al., 2020; Koch, 2016; Van Dyke, 2019).…”

Evaluating biological and oil‐based fungicides for dollar spot suppression on turfgrass

2020

Dollar spot (caused by Clarireedia jacksonii) receives more fungicide applications than any other turfgrass disease. Increasing restrictions on fungicide usage and expanding reports of fungicide resistant fungal populations have resulted in renewed interest in biological and plant-based control of turfgrass diseases. Six commercially available biological fungicides (Actinovate AG, Double Nickel LC, Nortica, Rhapsody, Serende Opti, Zio) and two oil-based fungicides (Civitas, Timorex Gold) were evaluated for dollar spot control on a creeping bentgrass putting green in Madison, WI, USA in 2017 and 2018. No biological or oil-based fungicide provided effective full-season dollar spot control compared to the synthetic fungicide boscalid. However, Civitas mineral oil provided levels of dollar spot control similar to boscalid on 9 of 12 rating dates over both years. The remaining treatments tested provided levels of dollar spot control and turf quality similar to boscalid ranging from 4 to 7 of a possible 12 rating dates. These results indicate that the biological fungicides tested here failed to provide commercially acceptable dollar spot control under moderate disease pressure in the midwestern U.S. The mineral oil Civitas did provide effective suppression under moderate disease pressure, while the tea tree oil Timorex Golf did not. Certain oil-based fungicides like Civitas can provide effective dollar spot control during periods of low to moderate disease pressure, but more research is needed before biological fungicides can be successfully integrated into a dollar spot management program.

“…The impetus for the latter includes reports of reduced pesticide requirements when using Civitas in a disease management program [3][4][5][6][7][8][9]. Having a unique mode of action relative to traditional fungicides, Civitas features a fungicide resistance action committee (FRAC) classification of "not" [10], is OMRI listed (Organic Materials Review Institute, Eugene, OR), and proves useful in organic management programs or where cosmetic pesticide use is prohibited.…”

Nitrogen (N) is the essential plant nutrient needed by turfgrass in the greatest quantity. Urea and urea-based liquids are arguably the safest, least expensive, and subsequently most popular soluble N fertilizers. Unfortunately, urea fertilizer application to turfgrass is often subject to NH3 volatilization: a deleterious phenomenon from both environmental and agronomic perspectives. The objective of this research was to quantify the efficacy of creeping bentgrass (Agrostis stolonifera L.) golf course fairway foliar fertilization by urea-based N fertilizers as influenced by a petroleum-derived spray oil (PDSO) containing Cu II phthalocyanine colorant (Civitas Turf DefenseTM Pre-M1xed, Intelligro LLC, Mississauga, ON, Canada). In 2019 and 2020, a maintained creeping bentgrass fairway received semimonthly 9.76 kg ha–1 soluble N treatment either alone or in combination with Civitas at a rate of 27 L ha–1. In the 48 h following foliar application, fertilizer N loss as NH3 ranged from 1.3 to 5.5% and corresponded directly to fertilizer urea content but not Civitas inclusion. In the 1 to 14 d following semimonthly treatment, Civitas had either a beneficial (methylol urea and UAN) or negligible (urea) effect on canopy mean dark green color index. Once cumulative N inputs exceeded 47 kg ha–1, creeping bentgrass fairway shoot growth and N nutrition were consistently increased by Civitas complementation of commercial liquid N fertilizer. Over the 2-yr study, absolute mean percent fertilizer N recovery from plots treated by Civitas-complemented foliar liquid N treatment exceeded their ’N only’ counterparts by 8.7%.
