Soybean induced resistance to Spodoptera eridania herbivory
Pest Management Science, EarlyView.SOD, CAT, APX, PPO, KTI, and MDA levels were higher in the resistant soybean. S. eridania herbivory increased H2O2 and MDA, but decreased SOD and PPO levels. S. eridania herbivory increased KTI activity only in the resistant variety. Isoquercitrin and daidzin were exclusive to resistant and susceptible soybeans.

Pest Management Science, EarlyView.The control efficacy of a novel laser pulse system operating at 1940 nm was tested. The new system allows effective control of young weeds with 1.5 J. Targeting the plant stem is 53‐fold more energy‐efficient than the meristem. Species morphology and beam diameter significantly influence weed control efficacy. Abstract BACKGROUND This study evaluates a

Reducing Risk of Weed Infestation and Labor Burden of Weed Management in Cropping Systems
, 2017 Weeds are a major biological yield reducing factor in most cropping systems in Africa. The annual cost of weed control has been estimated to be $4.3 billion in Africa. This figure is expected to increase as a result of climate change effects on weed species and ecological conditions for a range of weeds. Similarly, the labor burden that weeding imposes
