| Use | Use of pyrazole herbicides to kill weeds by inhibiting chlorophyll biosynthesis. Control annual and perennial weeds in rice fields. It is selective for rice and barnyard. It can inhibit their growth through the absorption of their roots in the seedling stage of wild barnyard, ducktongue, festival vegetables and beef felt, firefly, and narrow-leaf Alisma, and play a role in preventing weeds. effect. This product can be mixed with a variety of herbicides, and is willing to increase the effect, can play a role and effect that can not be used alone. For example, it is mixed with killing grass, inhibiting grass phosphorus and butachlor. Generally, it is used in rice fields before sowing or transplanting, with 3kg of effective ingredients per hectare. When applying, it is necessary to evenly spread 10% granules by hand or machine under the condition of water retention. |

Pyrazolate - Introduction
PYRAZOLATE(Pyrazolate) is an organic compound with the formula C6H5CH = N−N−CH2C6H5. It has a white or pale yellow crystalline solid and is soluble in some organic solvents.
PYRAZOLATE is mainly used as an intermediate for a variety of agricultural pesticides. It can be used as an active ingredient of insecticides or fungicides for controlling pests or pathogens on a variety of crops. PYRAZOLATE is widely used in agriculture because of its broad spectrum and high efficiency of insecticidal activity.
PYRAZOLATE is usually obtained by reacting benzaldehyde with hydrazine or hydroxyhydrazine. The reaction needs to be carried out under appropriate reaction conditions, for example under basic conditions to heat the reaction.
In terms of safety, PYRAZOLATE is less harmful to the human body under normal use conditions. However, the use of still need to follow the relevant safety guidelines. PYRAZOLATE may have toxic effects on non-target organisms such as fish and bees, so it should be used in accordance with relevant environmental protection regulations. At the same time, it is recommended to wear appropriate personal protective equipment during use, and avoid contact with skin, eyes or inhalation of dust. If you feel unwell or take PYRAZOLATE by mistake, you should seek medical attention immediately and take the relevant label or container to the hospital.
