The introduction of harvest weed seed control (HWSC) techniques and associated machinery has enabled the routine use an alternative technology at a novel timing in global grain cropping fields. Driven by significant threat widespread populations annual ryegrass (Lolium rigidum) with multiple-herbicide resistance, 1990s Australian growers researchers developed to target, harvest, production othe...

But recent relatively rapid change in climate occurs due to anthropogenic activities which makes alarming attention because it contributes largely to global warming by affecting the greenhouse gases (GHGs) and aerosols. GHGs mainly CO2, methane, nitr...

abstract in order to determine efficacy of some registered graminicides in control of resistant and susceptible ryegrass biotypes, two greenhouse trials were conducted at weed research department of iranian plant protection research institute during 2007. experimental design was completely randomized design with eight replications. the susceptible and resistant biotypes were treated by 19 herbi...

Experiments were established in 1999 to expand on the findings of 1997 and 1998 experiments that suggested corn hybrid yield potential was the most important factor to consider when making planting decisions. However, the previous experiments were conducted at only one location and contained only one hybrid for each herbicide resistant group. Many questions were raised concerning the validity o...

Rice bran application just after transplanting has been increasingly practiced as a herbicide-substitute for organic rice production in Korea. However, this practice is frequently reported to be unsatisfactory in weed suppression. An experiment with five treatments that combine flooding depth (shallow and deep), rice bran application level (low and high), and herbicide application was carried o...

Giant ragweed (Ambrosia trifida L.) and waterhemp (Amaranthus tuberculatus [Moq.] J.D.Sauer) are highly competitive the most troublesome weeds in corn (Zea mays soybean (Glycine max Merr.) cropping systems Wisconsin. Field experiments were conducted to evaluate efficacy of multiple foliar-applied POST-emergence herbicides on giant at Janesville, WI (2020 2021), groups 2- 9-resistant Brooklyn, (...

The synergistic interaction between mesotrione, a hydroxyphenylpyruvate dioxygenase (HPPD)-inhibiting herbicide, and atrazine, a photosystem II (PS II)-inhibiting herbicide, has been identified in the control of several weed species. A series of dose–response studies examined the synergistic effect of these herbicides on a susceptible (S) wild radish population. The potential for this interacti...
