“…A recent study performed in China evaluated various alternatives to MeBr, and found that fumigation with a combination of 1,3-dichloropropene and chloropicrin resulted in root-knot nematode control similar to MeBr, yet only moderately controlled weeds for tomato production (Qiao et al, 2015). The authors recommended adding herbicides to the two-fumigant combination.…”

Two years of field trials conducted in a Meloidogyne incognita-infested field evaluated grafting and Paladin Pic-21 (dimethyl disulfide:chloropicrin [DMDS:Pic] 79:21) for root-knot nematode and weed control in tomato and melon. Tomato rootstocks evaluated were; 'TX301', 'Multifort', and 'Aloha'. 'Florida 47' was the scion and the nongrafted control. A double crop of melon was planted into existing beds following tomato harvest. Melon rootstocks, C. metulifer and 'Tetsukabuto', were evaluated with nongrafted 'Athena' in year 1. In year 2, watermelon followed tomato with scion variety 'Tri-X Palomar' as the control and also grafted onto 'Emphasis' and 'Strongtosa' rootstocks. Four soil treatments were applied in fall both years under Canslit metalized film; Paladin Pic-21, methyl bromide:chloropicrin (MeBr:C33, 67:33), Midas (iodomethane:chloropicrin 50:50), and a herbicide-treated control. M. incognita J 2 in soil were highest in herbicide control plots and nongrafted tomato. All soil treatments produced similar tomato growth, which was greater than the herbicide control. All treatments reduced M. incognita J 2 in roots compared to the herbicide control. 'Multifort' rootstock produced the largest and healthiest roots; however, the number of M. incognita isolated from roots did not differ among the tomato rootstocks tested. Galling on tomato was highest in herbicide control plots and nongrafted plants. In melon, M. incognita J 2 in soil did not differ among melon rootstocks, but numbers isolated from melon rootstocks increased in 'Tetsukabuto' compared with C. metuliferus. 'Tetsukabuto' were larger root systems than nongrafted 'Athena'. All fumigants provided protection for all melon rootstocks against galling by M. incognita compared to the herbicide control. Galling on C. metuliferus rootstock was less in all fumigant treatments compared with nongrafted 'Athena' and 'Tetsukabuto'. In watermelon, M. incognita in soil and roots did not differ among soil treatments or watermelon rootstocks, and yield was lower in both grafted rootstocks compared with the nongrafted control. All soil treatments increased average fruit weight of watermelon compared with the herbicide control, and provided effective weed control, keeping the most predominant weed, purple nutsedge (Cyperus rotundus L.), density at or below 1/m row. Grafting commercial scions onto M. incognita-resistant rootstocks has potential for nematode management combined with soil treatments or as a stand-alone component in crop production systems.

“…Methyl bromide, which was widely used for soil fumigation in the past, was phased out globally by 2015 because of its ozone‐depleting property (Prather & Watson, 1990). It has been replaced by several fumigants including chloropicrin (PIC), dimethyl disulfide (DMDS), and dazomet (DZ; Gómez‐Tenorio et al., 2018; Gullino et al., 2002; Qiao et al., 2015). The “pesticide effect” of fumigants is the effective control of soil‐borne diseases and pests.…”

Background Soil fumigation is widely used as an effective way to control soil‐borne diseases and increase crop yield. Fumigants may also affect the bioavailability and mobility of soil trace elements (STEs) due to the inhibitory and biocidal effects of soil microorganisms. Aims Quantification of STEs fractions after fumigation would help us in understanding the role of fumigants on soil environment and provide valuable evidence on the explanation of the “fertilizer effect” of soil fumigants. The overall objective was to quantify the effects of soil fumigation on three main chemical fractions of nine STEs. Methods Effects of chloropicrin (PIC), dimethyl disulfide (DMDS), dazomet (DZ) on STEs were studied in three soils with standard and high dosages of fumigants. STEs fractions were detected using a modified Community Bureau of Reference three‐stage sequential extraction procedure. Results Results were evident in three farmland soils: (1) Among the nine elements, three fumigants had a significant impact on Mn and Co elements. Soils had a great complement to the bioavailable Mn and Co after fumigation. The content of Mn and Co in F1, the most available and transportable form for plants, significantly increased after fumigation with PIC, DMDS, and DZ. (2) Soil fumigation has an impact on Mn, Co, and other trace elements due to the process of Mn oxidation changed. Conclusions Our study suggested that the complement of bioavailable Mn and Co could be an important factor to promote plant growth and increase crop yield after soil fumigation.

“…In recent years, the population has shown more interest in acquiring a good quality of life including a balanced diet, which requires a regular consumption of fresh fruits and vegetables. Cherry tomato ( Lycopersicon esculentum Mill) fruits are of great importance in many countries for economic purposes ( Guo et al, 2014 ; Quiao et al, 2015 ), with a global production of fresh tomato fruits near 35,000 tons/year. The global consumption of tomato products is near 31,000 tons/year, with an average annual per capita consumption of ∼6 kg/inhabitant and fresh fruits represent near 75% of this consumption ( World Processing Tomato Council [WPTC], 2010 ).…”

Efficacy of a coating composed of chitosan from Mucor circinelloides and carvacrol to control Aspergillus flavus and the quality of cherry tomato fruits

Cherry tomato (Lycopersicon esculentum Mill) fruits are susceptible to contamination by Aspergillus flavus, which may cause the development of fruit rot and significant postharvest losses. Currently there are significant drawbacks for the use of synthetic fungicides to control pathogenic fungi in tomato fruits, and it has increased the interest in exploring new alternatives to control the occurrence of fungal infections in these fruits. This study evaluated the efficacy of chitosan (CHI) from Mucor circinelloides in combination with carvacrol (CAR) in inhibiting A. flavus in laboratory media and as a coating on cherry tomato fruits (25°C, 12 days and 12°C, 24 days). During a period of storage, the effect of coatings composed of CHI and CAR on autochthonous microflora, as well as on some quality characteristics of the fruits such as weight loss, color, firmness, soluble solids, and titratable acidity was evaluated. CHI and CAR displayed MIC valuesof 7.5 mg/mL and 10 μL/mL, respectively, against A. flavus. The combined application of CHI (7.5 or 3.75 mg/mL) and CAR (5 or 2.5 μL/mL) strongly inhibited the mycelial growth and spore germination of A. flavus. The coating composed of CHI (3.75 mg/mL) and CAR (2.5 or 1.25 μL/mL) inhibited the growth of A. flavus in artificially contaminated fruits, as well as the native fungal microflora of the fruits stored at room or low temperature. The application of the tested coatings preserved the quality of cherry tomato fruits as measured by some physicochemical attributes. From this, composite coatings containing CHI and CAR offer a promising alternative to control postharvest infection caused by A. flavus or native fungal microflora in fresh cherry tomato fruits without negatively affecting their quality over storage.
