Weed management in tropical turfgrass areas: A review

A review of non-chemical weed management

Turfgrass, crop, and weed hosts of Blissus occiduus (Hemiptera: Lygaeidae).

Blissus occiduus Barber is an important pest of buffalograss, Buchloë dactyloides (Nuttall) Engelmann, turf. No-choice studies documented the susceptibility of selected turfgrasses, crops, and weeds to B. occiduus feeding. Highly to moderately susceptible grasses included buffalograss; yellow Setaria glauca (L.) and green foxtail Setaria viridis (L.); Kentucky bluegrass, Poa pratensis L.; peren...

Weeds and Weed Management in India - A Review

India has a wide range of agroclimates and soil types. The highly diverse agriculture and fanning systems are beset with different types of weed problems. Weeds cause 10-80% crop yield losses besides impairing product quality and causing health and environmental hazards. Invasive alien weeds are a major constraint to agriculture, forestry and aquatic environment. Crop-specific problematic weeds...

Utilizing Iron In Turfgrass Management

D r. George Wallace a researcher from UCLA, writing in HortScience called the 1980s the decade for advancement in our knowledge of iron (Fe) and plant nutrition. He states: "More progress was perhaps made in the 1980s on understanding and management of Fe chlorosis in plants than during the previous 150 years since it became known that Fe deficiency was involved in the chlorosis." Iron is used ...

Modelling integrated weed management of an invasive shrub in tropical Australia

1. Where biocontrol programmes for invasive plants are in place, only one-third are fully successful. Integrated weed management (IWM) emphasizes the use of several complementary control measures. 2. We used models of increasing complexity to determine which parameters affect site occupancy of an invasive shrub, Mimosa pigra , in tropical Australia. Two introduced biocontrol agents have spatial...
