“…Similarly, previous studies reported that the use of DMDS plus chloropicrin consistently improves early and total marketable strawberry yields due to successful soilborne fungi and nematode control [25, 26]. Combination use of DMDS plus dazomet and DMDS plus 1,3-D can also improve the control efficacy on root-knot nematode and soilborne fungi [7, 27].…”

Root-knot nematode is an important soil pest in horticulture crops and constrains the protected cultivation development after methyl bromide (MB) was phased out in China. Dimethyl disulfide (DMDS) exhibits excellent efficacy against nematodes. Laboratory experiments and field trials were set up to clarify DMDS dose, efficacy, and yield. A dose-response experiment using three methods showed that DMDS presented high efficacy against the nematode Meloidogyne incongnita. The LC50 values of direct fumigation activity in the dessicator method were 0.086 and 0.070 mg L-1 for DMDS and 1,3-D, 29.865 and 18.851 mg L-1 for DMDS and 1,3-D of direct contact activity in the small tube method, 6.438 and 3.061 mg L-1 for DMDS and 1,3-D of soil fumigation activity in the soil fumigation method, respectively. The field trials indicated that DMDS showed an excellent efficacy of 80%−94% on root-knot nematode applied at 10−100 g m−2 on tomato in Tongzhou, Beijing. The crop yields showed no significant difference after applying 10–80 g m-2 DMDS. Results indicate that DMDS applied at 10 g m-2 for controlling root-knot nematode in Beijing is cost effective. In conclusion, DMDS is an excellent soil fumigant that can be used for controlling root-knot nematode and can be an potential novel alternative to MB in China.

“…In North China, cucumber ( Cucumis sativus L.) is among the most widely cultivated greenhouse vegetables. Soil-borne nematodes, weeds and fungi, exhibit a very strong potential to depress yields in protected cucumbers grown in greenhouses [ 1 , 2 ]. Methyl bromide (MB) has been widely used as a preplant soil fumigant to control soil-borne pathogens, nematodes and weeds in North China.…”

“…Sulfuryl fluoride [ 4 ], 1,3-dichloropropene (1,3-D) [ 1 , 5 – 7 ], dazomet (DZ) [ 7 ], chloropicrin (Pic) [ 8 ], 1,3-D/DZ [ 7 ], and 1,3-D/Pic [ 8 ] have also been confirmed as chemical alternatives that can be applied in place of MB to protect cucumbers in various countries, including China. However, these active substances do not offer as broad an activity spectrum as that provided by MB [ 2 , 9 ]. To expand the spectrum of action and achieve more effective control over soil-borne pests, combinations of single promising alternative fumigants have become the subject of increasing research in recent years.…”

Replacing methyl bromide with a combination of 1,3-dichloropropene and metam sodium for cucumber production in China

The combination of 1,3-dichloropropene (1,3-D) and metam sodium (MNa) is a potential resource to replace methyl bromide (MB) as a soil fumigant. The efficacy of 1,3-D+MNa as a crucial factor to limit soil-borne pests was evaluated in one laboratory experiment and two cucumber greenhouse studies conducted in commercial operations. Laboratory results revealed that 1,3-D and MNa (10+20 mg a.i. kg−1 soil) provided the best complementary control of the root-knot nematode, Fusarium oxysporum and two species of weed seeds. Greenhouse trials revealed that the blend of 1,3-D and MNa (10+20 g a.i. m−2) greatly inhibited the ability of Meloidogyne incognita to form root galls. In addition, the number of colony-forming units of F. oxysporum declined substantially after growth on media, resulting in higher fruit yields and greater economic benefits. The combined use of 1,3-D and MNa exhibited a higher control efficacy than when 1,3-D or MNa was utilized alone. The ability of this chemical combination to control soil-borne organisms did not differ significantly from the MB treatment and maintained high cucumber yields, enhancing the income of the farmers. Compared to the untreated control group, all the chemical treatments prominently improved the control of the pests. These results show that applying a combination of 1,3-D and MNa provides a promising alternative to MB that enables the sustained growth of cucumber production in China.

“…Cucumber (Cucumis sativus L.) is an important vegetable worldwide and is the second most popular crop planted in greenhouses (Sebastian et al, 2010;Mao et al, 2016). In China, cucumber has been cultivated for at least 3000 years, with cultivated acreage in 2012 estimated at 240,000 ha (Lv et al, 2012).…”

Root-knot nematodes (Meloidogyne spp) are destructive agricultural pests that reduce the productivity of cultivated vegetables worldwide, especially when vegetables are cropped continuously in greenhouses. Cucumbers (Cucumis sativus L.), in particular, suffer extensive damage due to root-knot nematodes, and only a few wild species are known to be resistant. Grafting of cultivated plants to rootstocks of known resistant germplasms could be an effective method to resolve this problem. In this study, 21 cucumber germplasms and seven rootstocks were evaluated for resistance based on the growth of cucumber seedlings and resistance indexes to Meloidogyne incognita, which were surveyed 25 days after inoculation with M. incognita. Cluster analysis and principal component analysis (PCA) were used to investigate the resistance of 21 cucumber germplasms and seven rootstocks based on their growth and resistance indexes after inoculation with M. incognita. These analyses showed that the 21 germplasms and seven rootstocks could be divided into three groups based upon their resistance levels: moderately resistant, susceptible, and highly susceptible to M. incognita. All 21 cucumber germplasms exhibited susceptibility or high susceptibility to M. incognita and most rootstocks exhibited moderate resistance. The PCA results were consistent with those of the clustering analysis. The Jinyou No.1 cultivar had the highest resistance to M. incognita among the 21 cucumber germplasms, and Huangzhen No.1 cultivar had the highest resistance among the seven rootstock cultivars.
