“…From our previous field and greenhouse studies (Zangoueinejad et al 2019), it was found that TOM199, TOM198, and TOM300 as wild tomato accessions are tolerant in their response to dicamba application at the drift rate (2.8 g a.e. ha −1 ).…”

Herbicide tolerance is commonly associated with reduced absorption and translocation of the herbicide; we hypothesized that the mechanism of dicamba tolerance in wild tomato (Solanum lycopersicum) accessions is due to these. The absorption and translocation of dicamba were investigated at a drift rate of 2.8 g ae ha-1, in three predetermined dicamba-tolerant wild accessions (TOM199, TOM198, and TOM300), and compared with two dicamba-susceptible (DS) commercial tomato cultivars [Money Maker (MM) and Better Boy (BB)]. Dicamba was quantified in three different parts of the tomato plant: two upper leaves, two lower leaves, and the roots, at 1, 3, and 7 days after treatment (DAT). Both MM and BB absorbed more dicamba then all the three DT accessions. The overall translocation pattern of dicamba was similar between DS cultivars and DT accessions, thus suggesting that tolerance to dicamba in wild accessions may not be associated with reduced translocation, but instead with reduced uptake of the herbicide. Additionally, reduced dicamba absorption in DT accessions may be attributed to their leaf characteristics, such as the presence of narrower leaves (3.42 leaf length/width ratio) and higher trichome density (20 no. mm-2) in DT accessions, than compared to DS cultivars (1.92 leaf length/width ratio, and 8 no. mm-2 trichome density).

“…Recently, Zangoueinejad et al (2019) evaluated the response of some selected wild tomato accessions to 2,4-D, dicamba, and quinclorac to the simulated drift rates of 11, 3, and 39 g ae ha −1 , respectively. Both greenhouse and field experiments confirmed the tolerance of three wild tomato accessions (TOM199, TOM198, and TOM300) by approximately 85% to 90% to dicamba, while they were sensitive to 2,4-D and quinclorac [27]. Earlier, Hu et al (2017) investigated the tolerance of several strawberry cultivars to different rates of terbacil (84, 168, and 336 g ae ha -1 ).…”

“…On the other hand, research into mitigation strategies should also be prioritized. The use of herbicide-tolerant crops within well-defined agroecological zones can improve weed management and preserve crop yield potential [27][28][29]38,39]. Good stewardship for herbicide application and herbicide-tolerant crops is important for sustainable weed management.…”

One of the most widely used auxinic herbicides in southern Iran’s cereal crop fields is 2,4-D; however, the concurrent growing season of off-season melons in this region potentially leads to herbicide drift from cereal fields to the melon fields. To study the response of some Iranian wild melon accessions to three simulated drift rates of 2,4-D, including 112.1, 11.2, and 3.7 g ae ha−1, a field experiment was conducted during 2019 and 2020 growing seasons. It was found that by increasing the herbicide rate from 3.7 to 112.1 g ae ha−1, the level of visual injury increased in all accessions. However, significant variation in herbicide tolerance was observed among different melon accessions. The MEL-R1 was the most tolerant accession with only 20% injury, while MEL-D8 displayed very high injury rate (ca. 90%) as assessed at 6 weeks after treatment during 2019. The accession MEL-S3 was the most tolerant to 2,4-D drift rates (20% injury) at 6 weeks after treatment during 2020. There was no significant difference between the accessions MEL-R1 and MEL-S3 in terms of their response to 2,4-D treatment during both years of the study, as these accessions fully recovered from injury over 6 weeks after herbicide treatment. In addition, only these two accessions were able to produce yield after the application of 2,4-D at the highest rate tested (112.1 g ae ha−1). Therefore, the melon accessions MEL-R1 and MEL-S3 could be recommended for cultivation and even for breeding programs in order to develop 2,4-D-tolerant commercial cultivars in regions where this herbicide is commonly used in cereal crop production adjacent to the melon fields.

“…According to Zangoueinejad et al (2019), three dicamba-tolerant wild tomato accessions (TOM199, TOM198, and TOM300) were identified, showing less than 15% visible injury against dicamba application at the rate of 2.8 g ae ha -1 . The aim of this current study was, therefore, to distinguish the potential tolerance level of these wild accessions in response to four rates, up to the drift rate (2.8 g ae ha -1 ) of dicamba, including 70, 140, 210, and 280 g ae ha -1 , through a doseresponse assay.…”

A greenhouse dose-response study was conducted to determine the tolerance of three wild tomato accessions (TOM199, TOM198, TOM300) in comparison to a commercial cultivar (Better Boy) against the dicamba application at five rates (0, 70, 140, 210, and 280 g ae ha-1) at 14 and 28 days after treatment (DAT). Several physiological traits were evaluated at 0, 1, 3, 5, and 7 DAT. Wild accessions and cultivar were killed at all rates above 70 g ae ha-1 at 14 and 28 DAT, which is why differences between accessions and cultivar were only evident at 70 g ae ha-1. The GR50 (the herbicide rate that causes 50% reduction in dry weight) of Better Boy was 4.4 g ae ha-1 at 28 DAT, and this cultivar was approximately 11-fold more sensitive than wild accessions. At 7 DAT, the levels of H2O2 for wild accessions were lower than Better Boy up to 5 at 70 g ae ha-1 of dicamba. Furthermore, wild accessions showed lower herbicide absorption than Better Boy at all dicamba doses at 1, 3, and 7 DAT. All the three wild accessions expressed tolerance to the dicamba application at the dose of 70 g ae ha-1. At the same time, Better Boy and wild accessions were susceptible to dicamba application at rates of 140, 210, and 280 g ae ha-1.
