STRUCTURE AND PRODUCTIVITY OF TANZANIA GRASS SUBJECTED TO DIFFERENT DEFOLIATION FREQUENCIES

Ciência Animal Brasileira, 2017
The objective of the present study was to evaluate the effect of different frequencies of defoliation at fixed periods on the structural and productive characteristics of Tanzania grass (Panicum maximum) under Am climate conditions in 2014.

Soybean induced resistance to Spodoptera eridania herbivory

Pest Management Science, Volume 82, Issue 10, Page 9931-9943, October 2026.
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.

Water Management for Defoliation

, 2015
Reviewed 06/2015; Originally published 02/20012 pp.There are several factors which are important to consider in managing defoliation. Factors such as plant-water relations, Nitrogen (N) fertility status, the extent of honeydew deposits on the leaves from

The Role of Environmental Parameters in the Evolution of Holm Oak (Quercus ilex L. subsp. ballota (Desf.) Samp) Decline: Studies in the Iberian Peninsula

Forest Pathology, Volume 56, Issue 5, October 2026.
ABSTRACT The combination of geographical factors (climate, slope, orientation, lithology, water availability, etc.) and the pathogenicity of agents such as the oomycete from the kingdom Straminopile Phytophthora or Pythium species causes the plant disease known as oak decline in the Iberian Peninsula. Leaving aside the presence of the pathogen, the aim

MORFOLOGIC CHARACTERIZATION ON MARANDU GRASS PASTURES SUBMITTED TO DEFOLIATION FREQUENCIES AND FERTILIZATION LEVELS

Ciência Animal Brasileira, 2017
Tillers are the basic units of growth in forage grasses and tillering is responsible for the adaptation and reestablishment of grass after defoliation.

Plant genotypic diversity and defoliation jointly shape root exudation, fungal communities, and carbon and nitrogen cycling

New Phytologist, Volume 252, Issue 1, Page 324-339, October 2026.
Experimental design. Summary Intraspecific plant diversity is a major component of community diversity, yet its role in shaping plant–microbial interactions and soil functioning remains poorly understood. In particular, plant genotypic diversity may modulate ecosystem responses to defoliation, a key driver of ecosystem processes in grazed systems.

Evaluating early‐season hail damage in corn and its interaction with Goss's wilt

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Hailstorm losses are associated with plant defoliation, stand losses, and reduced crop canopy capacity to compete with weeds. Additionally, hail wounds in plants might favor disease development, potentially further reducing corn yields. Corn yield losses due to hailstorms early in the growing season are considered minor due to an expected ...

Comparative evaluation of nonlinear disease progress models for quantitative assessment of peanut leafspot disease

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Leafspot disease causes up to 70% yield losses in peanut production areas across the globe. One way to curb this menace is to use leafspot resistant peanut (Arachis hypogaea L.) varieties. In breeding for disease resistance, quantitative characterization of disease dynamics, including initial inoculum (y0) and apparent infection rate (r), is ...

Effects of uncrewed aerial vehicle–applied triclopyr plus fluroxypyr rates on weeds and desirable forbs in Kansas tallgrass prairie

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract We studied the impacts of uncrewed aerial vehicle (UAV)‐applied triclopyr + fluroxypyr on rangeland weeds and other forbs in native tallgrass prairie. Two rates were tested: high (0.63 kg ae ha−1 triclopyr + 0.21 kg ae ha−1 fluroxypyr) and low (0.21 kg ae ha−1 triclopyr + 0.07 kg ae ha−1 fluroxypyr).
