Watermelon gummy stem blight (GSB) management using a green manure cover crop, the weather-based disease forecasting program ‘Melcast,’ and bio- and reduced-risk fungicides was evaluated in Maryland. Soil incorporation of hairy vetch winter cover crop suppressed percent foliage affected by GSB in comparison to winter fallow in three of five trials conducted in 2004 and 2005. Programs of Reynoutria sachalinensis, Bacillus subtilis, or harpin protein applied in rotation with chlorothalonil provided control of GSB as effectively as did EBDC, boscalid, or cyprodinil plus fludioxonil. However, the bio-fungicide programs did not perform as well as chlorothalonil alternated with pyraclostrobin plus boscalid in 2005. Melcast-scheduled sprays of B. subtilis in rotation with chlorothalonil resulted in an average of 73% less synthetic fungicide applied to watermelon. However, GSB reduction in the B. subtilis program, although similar in 2005, was less that that obtained with chlorothalonil alone in 2004. These results suggest that the combined use of green manure with Melcast-scheduled fungicide applications could effectively manage GSB and reduce fungicide use. Biofungicides alternated with chlorothalonil also minimized use of synthetic fungicides and were effective under some conditions, but should be used with caution.

Reynoutria Sachalinensis

Basil downy mildew (BDM), caused by the fungus-like oomycete pathogen Peronospora belbahrii, has become a destructive disease of sweet basil (Ocimum basilicum). Without proper management, BDM can cause complete crop loss. Currently, there are no commercially available sweet basil cultivars with genetic resistance to BDM. Because BDM is a relatively new disease of basil in the United States, there are few currently registered conventional or organic fungicides labeled for its control. Fungicide efficacy trials were conducted in 2010 and 2011 at Rutgers Agricultural Research and Extension Center in Bridgeton, NJ. During both years, seven biological fungicide treatments were field evaluated, including hydrogen dioxide; extract of Reynoutria sachalinensis; Bacillus pumilus strain QST 2808; a mixture of rosemary oil, clove oil, and thyme oil; mono- and dipotassium salts of phosphorous acid; sesame oil; copper hydroxide; and a combination of sesame oil + cupric hydroxide. Six conventional fungicides evaluated included mandipropamid, fluopicolide, propamocarb hydrochloride, cyazofamid, azoxystrobin, and fenamidone. In both years, mono- and dipotassium salts of phosphorous acid provided the best control. Moderate disease suppression was provided by mandipropamid, cyazofamid, and fluopicolide compared with the control in 2010 and mandipropamid, cyazofamid, and copper hydroxide compared with the control in 2011.

Regalia®, a commercial extract of giant knotweed [Fallopia sachalinensis F. Schmidt (synonyms: Reynoutria sachalinensis (F. Schmidt) Nakai, Polygonum sachalinense F. Schmidt, Tiniaria sachalinesis (F. Schmidt) Janch.)], was evaluated for its potential to enhance drought tolerance of container-grown impatiens (Impatiens walleriana Hook. f. ‘Super Elfin XP White’). In two separate experiments, Regalia® was foliar-applied once a week for 4 weeks at four different rates (0, 5, 10, or 15 mL·L−1). In Expt. 1, Regalia® was applied to impatiens grown under three target substrate volumetric water contents (TVWCs): 85%, 55%, or 25%. In Expt. 2, Regalia® was applied to impatiens watered with 1, 3, or 6 days between waterings (DBW). In Expt. 1, root dry weight (RDW) of impatiens receiving applications of Regalia® at the 0.5× rate was greater compared with the 0.0× rate across all TVWCs. Additionally, soluble protein content was greater after Regalia® application at the 0.5×, 1.0×, or 1.5× rates compared with the 0.0× rate for plants grown at 55% TVWC. In Expt. 2, leaf greenness (SPAD) and leaf net photosynthetic rate (Pn) were greater with Regalia® applied at the 0.5× and 1.0× rates compared with the 0.0× rate, respectively. Soluble protein content was greater in impatiens treated with Regalia® at the 1.5× rate and 1 DBW and the 0.5× rate with 3 DBW compared with the 0.0× rate with 1 or 3 DBW. However, there was no indication that impatiens grown under different moisture levels had increased drought tolerance after application of Regalia®.

Existing Data

Invasive alien species Ludwigia peploides, Reynoutria sachalinensis and Nicotiana glauca, currently registered in Croatia with small number of records, were found during fieldwork undertaken mostly through the national monitoring of waters from 2018 to 2020. Ludwigia peploides was previously recorded only once in the River Ilova, the existing data for R. sachalinensis indicate only three confirmed findings, in Čabar, Karlovac and Donja Stubica, while the previous data for N. glauca include several localities in Central and Southern Dalmatia. The new records are as follows: two findings of L. peploides refer to the River Česma (Obedišće and Sišćani); three records of R. sachalinensis refer to Gorski Kotar (Gerovo and Čabar), while N. glauca is newly recorded in the Neretva River Valley (Krvavac) and the island of Krk. Despite their potential invasiveness, all three are still locally naturalized and currently their spread is very slow and limited in Croatia.

AbstractActivated carbons from biomass material of giant knotweed Reynoutria sachalinensis (F. Schmidt ex Maxim.) Nakai were obtained. Use of this plant for manufacturing activated carbon has not been studied yet. Therefore, the first activated carbons of giant knotweed origin are described. Both physicochemical (by steam and CO2) and chemical (by KOH) activation methods were applied. Influences of temperature (500, 600, 700 and 800°C), burn-off [10, 25 and 50 wt. % (daf)] and KOH concentration on pores surface area and volume distribution of the obtained activated carbons were explored. Porosity of the elaborated sorbents was determined by benzene and carbon dioxide sorption measurements. Sorbents obtained by steam activation were micro- and mesoporous with surface area and volume of pores increasing with temperature and burn-off to V = 0.351 cm3 g-1 and S = 768 m2 g-1 at 800°C at 50% burn-off. Carbon dioxide activation resulted with notably microporous activated carbons with porous texture parameters also increasing with burn-off to V = 0.286 cm3 g-1 and S = 724 m2 g-1 at 50% burn-off. The highest BET surface area of 2541 m2 g-1 was achieved when chemical (KOH) activation was performed using KOH to char ratio 4:1.
