Among five groups of albino mice, three were treated with plant's extract, in addition, a group treated with t...

Weed management is a major issue in organic farming systems. Although interseeding cover crops is one alternative to herbicides, cover crops often suppress not only weeds but also main crops. Therefore, using cover crops for weed control without adverse effects on main crop growth is important. To verify the effect of cover crops on competition between main crops, cover crops and weeds in snowy...

Abstract The Japanese beetle Popillia japonica is an invasive alien species recently introduced and established in Northern Italy. Adult beetles are very polyphagous feed on vines, fruit trees, forest crops, vegetables, ornamental wild plant species. Eggs usually laid by females moist grassland the summer, singly or small clusters. Larvae roots may be transported soil of plants for planting gro...

abstract in order to determine the critical period of weed control in euro-flour variety of sunflower (helianthus annus, l.) an experimental was conducted with a randomized complete block design with 10 treatments and three replications in islamic azad university astara-branch-agricultural college in 2006 growing season. experimental treatments were conducted in two sets, the first set included...

russian knapweed (acroptilon repens l.) is a perennial weed of aceraceae that is becoming a dominant weed in suitable conditions. in order to find an ecological non-chemical approach for controlling russian knapweed and studying the possibility of using flower-eater mite (aceria acroptiloni shevchenko & kacalev) (acari: eriophyidae), a series of studies including field survey and field experime...

The use of depth cameras in precision agriculture is increasing day by day. This type of sensor has been used for the plant structure characterization of several crops. However, the discrimination of small plants, such as weeds, is still a challenge within agricultural fields. Improvements in the new Microsoft Kinect v2 sensor can capture the details of plants. The use of a dual methodology usi...

A new aerial platform has risen recently for image acquisition, the Unmanned Aerial Vehicle (UAV). This article describes the technical specifications and configuration of a UAV used to capture remote images for early season site- specific weed management (ESSWM). Image spatial and spectral properties required for weed seedling discrimination were also evaluated. Two different sensors, a still ...

Uncontrolled growth of weeds can severely affect the crop yield and quality. Unrestricted use herbicide for weed removal alters biodiversity cause environmental pollution. Instead, identifying weed-infested regions aid selective chemical treatment these regions. Advances in analyzing farm images have resulted solutions to identify plants. However, a majority approaches are based on supervised l...

Effects of water stress and Fusarium oxysporum f. sp. lycoperseci (Fol) on the growth of tomatoes were studied in a greenhouse experiment. Treatments consisted of five levels of water stress (1, 3, 5, 7 and 9 day irrigation intervals). Infested soil consisting of 400 chlamydospores g1 of Fol and non infested soil were used. Experiments arranged in a completely randomized design with 8 replicati...

Uncontrolled weeds cause considerable losses in the grain yield of pigeonpea. Field experiments were conducted for seven years from 1998 to 2004 on a loamy sand soil to study the effect of weed management on weeds, growth and grain yield of pigeonpea. In some years, weed dry matter was higher than in others, due to variation in rainfall received. Two hand weedings, pendimethalin in integration ...
