“…As negative effects on plant growth were also observed in noninoculated lentil grown in KN03-supplemented plant nutrient solution, this suggests that metribuzin treatment primarily affects plant growth rather than R. leguminosarum activity. Detrimental effects of photosynthesis-inhibiting herbicides on both inoculated and noninoculated legumes have been observed by others (Bollich et al 1985;Fischer and Tasistro 1982;Friesen and Wall 1986;Kao and Wang 198 1 ;Ladlie et al 1977;Mallik and Tesfai 1985). Rennie and Dubetz (1984) reported that while metribuzin applied preemergence on soybean decreased germination and plant growth, C2H2 reduction activity was higher than for control plants.…”

The effects of the triazine herbicide metribuzin (Sencor) on the lentil (Lens culinaris Medic.) - Rhizobium leguminosarum biovar viciae symbiosis were studied in Leonard jars and growth pouches. Lentils inoculated with Rhizobium leguminosarum strain 128C54 or 128C84, and noninoculated lentils grown in plant nutrient solution supplemented with 5 mM KNO3, had metribuzin applied to the plants at either 8 or 13 days after planting. When sprayed at 8 days, metribuzin had a significant (p less than or equal to 0.05) negative effect on plant weight, number of nodules, taproot growth, and acetylene reduction activity. Five to 10 days after spraying, the plants began to recover from the inhibitory effects. When spraying was delayed to 13 days after planting, metribuzin had little effect on plant growth. The R. leguminosarum strain used as inoculant affected the degree of inhibition of lentil growth and the rate of plant recovery. Less than 0.2% of foliarly applied metribuzin was translocated to the root. Thus the detrimental effects of metribuzin application to lentils were mainly due to direct effects on the plant, which resulted in indirect effects on nodulation and nitrogen fixation.

“…Reduced uptake of xylem-mobile triazine herbicides was observed in soybean [Glycine max (L.) Merr.] plants treated with root inhibitory dinitroaniline herbicides (Ladlie et al 1977). A similar mechanism reduced simazine injury to ornamentals by 40 to 80% when tank mixed with oryzalin or napropamide (Ryan et al 1981).…”

Greenhouse experiments evaluated azafenidin and thiazopyr applied separately, as a tank mix, or in rapid succession, for preemergence control of yellow nutsedge (Cyperus esculentus) and hairy beggarticks (Bidens pilosa). Average of yellow nutsedge shoot dry weights at 21 and 42 d after treatment (DAT), indicated that azafenidin at 0.28, 0.56, and 1.12 kg ai/ha controlled 70, 86, and 90%, respectively, and thiazopyr at 1.12 kg/ha controlled 10% of yellow nutsedge. However, when thiazopyr at 1.12 kg/ha was tank-mixed with azafenidin at 0.28, 0.56, and 1.12 kg/ha, yellow nutsedge control averaged for 21 and 42 DAT was reduced to 41, 69, and 78%, respectively. Root plus tuber dry weight of yellow nutsedge increased threefold when 1.12 kg/ha thiazopyr was mixed with 0.28 kg/ha azafenidin, compared to azafenidin applied alone at the above rate. When the herbicides were applied sequentially, within minutes of each other, the antagonistic responses were reproduced, independent of the order of herbicide application. Thiazopyr applied at 0.56 and 1.12 kg/ha stimulated the emergence and establishment of hairy beggarticks and antagonized azafenidin for the control of yellow nutsedge based on a mathematical model. Although thiazopyr reduced the preemergence herbicidal efficacy of azafenidin on hairy beggarticks control, antagonism could not be determined because of the stimulatory effects of thiazopyr on hairy beggarticks emergence.

“…Interactions can take place between herbicides in soil. Ladlie et al (1977) reported that on a high-pH soil, trifluralin plus metribuzin caused less injury to soybean compared with a single application of metribuzin. Results from greenhouse studies indicated that trifluralin also reduced corn injury from atrazine.…”

A 2-yr field study was conducted to evaluate the response of rice to rotational crop herbicides in combination with rice herbicides in water-seeded culture. Fluometuron, imazethapyr, metolachlor, and norflurazon were applied at 0.5, 0.25, 0.125, and 0.063 times the recommended use rates preplant incorporated (PPI) to simulate herbicide carryover from previous crops. Molinate and thiobencarb at 4.5 kg ai/ha were applied PPI, and quinclorac at 0.43 kg ai/ha postemergence. No interaction between rice herbicides and rotational crop herbicides was observed for rice injury at 4 wk after planting (WAP), plant dry weight, stand, and height at 8 WAP, or rice grain yield. However, rice heading was delayed with some rotational crop herbicide and rice herbicide combinations. Fluometuron at the 0.5 and 0.25× rates injured rice 64 and 21% at 4 WAP, and reduced rice yield 96 and 20%, respectively. At 4 WAP, metolachlor at the 0.5 and 0.25× rates injured rice 93 to 29%, and reduced rice yield 85 to 20%, respectively. An 84 to 100% rice injury at 4 WAP and a 81 to 100% rice yield reduction were observed with norflurazon at the 0.5 and 0.25× rates, respectively. Imazethapyr caused 15 to 26% rice injury 4 WAT and 22 to 41% yield reduction.
