The present invention can provide a method exerting an excellent control effect in the control of glyphosate-resistant weeds. The method includes the step of applying to 200 g per 10000 m.sup.2 of trifludimoxazin to the glyphosate-resistant weed or a habitat of the glyphosate-resistant weed.

Granular compositions comprising at least one herbicide that inhibits microtubule assembly, at least one herbicide that inhibits cell wall synthesis, and a surfactant, and methods for making and using such compositions, are generally described.

Provided herein are high-load emulsifiable concentrate compositions containing at least 875 g/L haloxyfop ester, a solvent, and a surfactant. The concentrate compositions leave less than 3.9 weight percent residue upon pouring at 5° C.

The present disclosure provides the use of 4-(Phenylethynyl) benzoic acid in preparing a plant growth regulator. 4-(Phenylethynyl) benzoic acid has a formula as C.sub.15H.sub.10O.sub.2, a molecular weight of 222.2390. The optimum concentration of 4-(Phenylethynyl) benzoic acid in the plant growth regulator is in a range of 10 μM to 200 μM. The plant growth regulator further contains a pesticidally acceptable carrier. The present disclosure further provides the use of 4-(Phenylethynyl) benzoic acid in regulating plant growth. In the use of 4-(Phenylethynyl) benzoic acid in preparing a plant growth regulator of the present disclosure, 4-(Phenylethynyl) benzoic acid has the ABA-like effects, and is more stable, easily available, cheaper, and environmentally friendly. Therefore, the present disclosure is suitable for large-scale popularization.
