Roundup - - a new perennial weed killer

open access: yesCalifornia Agriculture, 1973
Perennial weeds are an increasingly important problem in California. This may be due in part to the increased use of preemergence herbicides which reduce the competition to perennial weeds from the normally more prevalent, faster growing, annual weed ...

Response of Zoysiagrass Cultivars to Preemergence Herbicides

Journal of Turfgrass Management, 1996
ABSTRACT A field experiment was conducted over a 2-year period to evaluate the tolerance of five creeping bentgrass (Agrostis stolonifera L.) cultivars to preemergence herbicides. There was no herbicide-by-cultivar interaction. All herbicides applied at recommended rates maintained an acceptable quality (> 92% of untreated) throughout the spring and ...

Preemergent Herbicides for Cantaloupe and Watermelon

Journal of Vegetable Crop Production, 1995
The preernergence applied herbicides tested provided acceptable weed control in watermelon and cantaloupe for one month after planting. Plots treated with ethalfluralin had satisfactory yields, good weed control, and no crop injury. Bensulide and the sodium salt of naptalam in combination also resulted in satisfactory weed control for one month after ...

The preemergency state of a hydraulic unit

Journal of Machinery Manufacture and Reliability, 2010
The approaching emergency state of a hydraulic unit is analyzed when it can be due to the loosening of fixtures and the intensification of proper and induced vibrations accompanied by frequency beating and collisions of the structural components.

Factors Affecting Performance of Preemergence Herbicides

Weed Science, 1968
Spray and granular forms of isopropyl N-(3-chlorophenyl)-carbamate (CIPC, ethyl N,N-dipropylthiocarbamate (EPTC), a,a,a-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine (trifluralin) and 2,4-bis(isopropylamino) -6-methylmercapto-s-triazine (prometryne) were incorporated preemergence to barnyardgrass Echinochloa crusgalli (1.) Beauv.) and broadleaf weeds ...

Amiben and Diuron Preemergence in Castorbeans

Weeds, 1966
Although selectivity was low, 3-(3,4-dichlorophenyl)-1,1-dimethylurea (diuron) gave excellent preemergence weed control when castorbeans (Ricinus communis L.) were planted 2 or 3 in deep. Excellent weed control with little crop injury by 3-amino-2,5-dichlorobenzoic acid (amiben) was provided also and selectivity was not affected by depth of planting.
