HELIOSEISMOLOGY OF PRE-EMERGING ACTIVE REGIONS. III. STATISTICAL ANALYSIS [PDF]
The Astrophysical Journal, 2014 The subsurface properties of active regions prior to their appearance at the solar surface may shed light on the process of active region formation. Helioseismic holography has been applied to samples taken from two populations of regions on the Sun (pre-emergence and without emergence), each sample having over 100 members, that were selected to ...

Pre-Emergence Rotting of Peas in South Australia [PDF]
Australian Journal of Biological Sciences, 1964 Laboratory tests have shown that individual wrinkle-seeded pea seeds vary in their ability to continue vigorous growth after germination. After the radicle has broken through the testa, SOme produce normal seedlings, some fail to develop further, while others afe intermediate between these extremes and produce stunted seedlings. Thus some seeds capable

Chemical Control of Morning Glory Species in Sugarcane Harvested in the Dry and Semi-Wet Seasons1 [PDF]
Planta Daninha, 2016 The control of morning glory (Ipomoea spp. and Merremia aegyptia) was evaluated in five commercial sugarcane-production fields receiving applications of the herbicides sulfentrazone (0.9 kg ha-1), amicarbazone (1.4 kg ha-1), imazapic (0.147 kg ha-1), and

The implications of spatially variable pre-emergence herbicide efficacy for weed management [PDF]
, 2017 BACKGROUND The efficacy of pre-emergence herbicides within fields is spatially variable due to soil heterogeneity. We quantified the effect of soil organic matter on the efficacy of two pre-emergence herbicides; flufenacet and pendimethalin, against A.

Development of the novel pre-emergence herbicide pyroxasulfone
Japanese Journal of Pesticide Science, 2016 Pyroxasulfone, which was discovered and developed by K-I Chemical Research Institute Co., Ltd.; Kumiai Chemical Industry Co., Ltd.; and Ihara Chemical Industry Co., Ltd., is a novel pre-emergence herbicide for wheat, corn, and soybean. Pyroxasulfone inhibits the biosynthesis of very-long-chain fatty acids in plants and has shown excellent herbicidal ...
