How do you control weedy rice?
However, weedy rice plants growing taller than cultivated rice can be controlled by treating them with foliar herbicides such as glyphosate or cycloxydim at 20 and 5% concentrations, respectively, by using a wiper/wick applicator [37]. This technology helps in reducing viable seed setting/production.

How does flooding rice fields reduce the need for herbicides and pesticides in rice farming?
Explain how flooding rice fields reduces the need for herbicides and pesticides in rice farming. Rice has a submerged growth state while most weeds do not. Therefore, flooding rice fields reduces the growth of these less robust pests without negatively affecting the rice crop.
Which herbicide is used to control weeds in transplanted rice?
In transplanted rice, hand weeding twice on 15 – 20 DAT and 45 DAT will control the weeds effectively (or) Pendimethalin 3.0 lit/ha at 8 DAT with optimum moisture condition and one hand weeding on 45 DAT.

At what time do you need to apply herbicides in rice and corn?
Some specific 2,4-D products may indicate seven to 14 days prior to planting corn and 30 days prior to planting rice, depending upon rate applied. University data agrees that these are accurate for corn and rice to allow for the best crop safety.
What is the purpose of strip cropping?
Strip cropping helps to stop soil erosion by creating natural dams for water, helping to preserve the strength of the soil. Certain layers of plants will absorb minerals and water from the soil more effectively than others.
How do organic farming practices relate to soil health?
Higher Matter. Soils rich in organic matter hold more air and water and produce higher yields than soils low in organic matter. They also supply a steady release of nutrients to plants, inhibit erosion, and host a robust population of beneficial microorganisms.
Who discovered wild rice?
Growing wild rice as a field crop was first suggested in 1852 by Joseph Bowron from Wisconsin, and in 1853 by Oliver H. Kelley of Minnesota. Efforts to grow wild rice as a field crop did not begin until 1950. James and Gerald Godward grew wild rice in a one-acre diked, flooded field (paddy) near Merrifield, Minnesota.
