“…For drip irrigation, CNAP appears to be more rapidly delivered to the leaves than TCAP, as the distribution of content in the middle and upper leaves is higher than in the roots by day 5, compared to 15 days for TCAP. This may be related to the nature of the agent itself, and our results are also in general agreement with the results of the indoor trials by Fan et al 22 . This provides an important reference for drip irrigation applications of both agents to control corn pests, with TCAP being used primarily to control pests that mainly affect the roots of corn, while CNAP can be used primarily for pests that damage the middle and upper parts of corn, thus achieving precise control of the pests.…”

“…6,30 Some studies suggest that the deposition of volatile gaseous pesticides from the soil or the deposition of resuspended soil particles in the above-ground part of the plant also contributes to the accumulation of pesticides in the above-ground part. 31,32 This may also be the reason for the discrepancy between our results and those of Fan et al, as their results were based on corn grown indoors by hydroponics, 22 whereas ours were field-grown corn. is also clear from our results that the ability of the agent to translocate to the leaves is significantly stronger than to the stem, which explains why the agent stays in the leaves longer, even up to 40 days, through drip irrigation (Supporting Information Table S5).…”

BACKGROUND: As the use of diamide insecticides on corn continues to increase, there is growing concern about their residue levels on corn and dietary risks to populations. In this study, the distribution, dispersion and transfer efficiency of two diamide insecticides (tetrachlorantraniliprole (TCAP) and cyantraniliprole (CNAP)) in different parts of corn and soil were investigated in a 1-year field trial in Guangzhou and Lanzhou using two different application methodsspray and drip irrigation, respectivelyand the dietary risk of the insecticides to different consumer populations was assessed under the two application methods. RESULTS:The results showed that drip irrigation had a longer persistence period than spraying, and there was a hysteresis in the absorption distribution of the agent in different parts of corn, which was gradually transferred to the leaves after absorption from the roots. The average TE 1 (transfer efficiency) and TE 2 were 0.230-0.261 and 1.749-1.851 for TCAP and 0.168-0.187 and 2.363-2.815 for CNAP, respectively. At corn harvest, both TCAP and CNAP were below detectable levels in soil and corn. For different consumer populations, hazard quotients ranged from 0.001 to 0.066 for TCAP and from 0.003 to 0.568 for CNAPboth well below 100%.CONCLUSION: This study indicates that TCAP and CNAP applied by spray or drip irrigation are safe for long-term risk of human intake and also provides guidance for the use of both insecticides in agricultural production to control corn pests, especially in arid and semi-arid areas.

“…Thus, oxathiapiprolin and famoxadone with low solubility and high log K ow preferentially accumulate in the cell walls or organelles, which reduces their mobility in the protoplasm and translocation capacity to the shoots. Similarly, tetrachlorantraniliprole (Tca) with log K ow = 5.719 is mainly stored in the cell walls of wheat, which poses difficulty for upward transportation . However, not all pesticides easily accumulate in insoluble components.…”

The uptake, translocation, and subcellular distribution of oxathiapiprolin and famoxadone in tomato plants were investigated using hydroponic experiments. Oxathiapiprolin and famoxadone mainly accumulated in the tomato roots with limited translocation capacity from the roots to the upper part. The root absorption and inhibitor results noted the dominance of the apoplastic and symplastic pathways in the oxathiapiprolin and famoxadone uptake by the tomato roots, respectively. Furthermore, the uptake process for the two fungicides followed passive and aquaporin-dependent transport. Insoluble cell components (cell organelles and walls) were the dominant storage compartments for oxathiapiprolin and famoxadone. In the protoplast, oxathiapiprolin in the soluble fraction had a higher proportion than that of famoxadone. Finally, the uptake and distribution of the two fungicides by the tomato plants was accurately predicted using a partition-limited model. Thus, this study provides an in-depth understanding of the transfer of oxathiapiprolin and famoxadone from the environment to tomato plants.

BACKGROUNDThe insecticide carbosulfan is usually applied as a soil treatment or seed‐coating agent, and so may be absorbed by crops and pose dietary risks. Understanding the uptake, metabolism and translocation of carbosulfan in crops is conducive to its safe application. In this study, we investigated the distribution of carbosulfan and its toxic metabolites in maize plants at both the tissue and subcellular levels, and explored the uptake and translocation mechanism of carbosulfan.RESULTSCarbosulfan was mainly taken up by maize roots via the apoplast pathway, was preferentially distributed in cell walls (51.2%–57.0%) and most (85.0%) accumulated in roots with only weak upward translocation. Carbofuran, the main metabolite of carbosulfan in maize plants, was primarily stored in roots. However, carbofuran could be upwardly translocated to shoots and leaves because of its greater distribution in root‐soluble components (24.4%–28.5%) compared with carbosulfan (9.7%–14.5%). This resulted from its greater solubility compared with its parent compound. The metabolite 3‐hydroxycarbofuran was found in shoots and leaves.CONCLUSIONCarbosulfan could be passively absorbed by maize roots, mainly via the apoplastic pathway, and transformed into carbofuran and 3‐hydroxycarbofuran. Although carbosulfan mostly accumulated in roots, its toxic metabolites carbofuran and 3‐hydroxycarbofuran could be detected in shoots and leaves. This implies that there is a risk in the use of carbosulfan as a soil treatment or seed coating. © 2023 Society of Chemical Industry.
