Effects of 1,3-dichloropropene on nematode, weed seed viability and soil-borne pathogen

Evaluation of the combination of 1,3‐dichloropropene and dazomet as an efficient alternative to methyl bromide for cucumber production in China

“…The major adopted alternatives to MB include fumigants and other chemical pesticides, applied alone or as mixtures 5. 1,3‐Dichloropropene (1,3‐D)6–8 and chloropicrin (Pic)9, 10 (especially as 1,3‐D/Pic formulations),11 are the most common fumigant alternatives adopted, followed by Pic, metham sodium (MNa)12, 13 and dazomet (DZ) used alone. Combinations of 1,3‐D, Pic, metham and DZ,4 with or without low permeability barrier films (LPBFs) or additional herbicides14, 15 and fungicides, or other non‐chemical alternatives,16 have been shown to be as effective as MB in many trials and in commercial practice.…”

Effects of organic and conventional pesticides on plant biomass, nematode diversity and the structure of the soil food web

Evaluation of chemical alternatives to methyl bromide in tomato crops in China

“…This was also the case in this study, in which CP and DZ did not control weeds as effectively as MB. Most previous studies indicated that the fumigants tested in this study could only offer moderate control of pathogens and weeds (Qiao et al, 2010). Variations in these studies may be due to the fact that the efficacy of these fumigants is dependent upon achieving an appropriate soil structure and moisture content at application followed by effective sealing of the soil surface to reduce loss of these fumigants.…”
