The use of herbicides in the low temperature period is not conducive to the exertion of the drug effect, and the lethality to weeds is low. Therefore, it is necessary to have reasonable methods and measures to improve the efficacy of the herbicides at low temperature. Xiaobian summarizes the following three points for you:
First, grasp the concentration of application.
Accurate water consumption, suitable pesticide concentration can improve the herbicidal effect to ensure uniform application and prevent phytotoxicity, so as to improve the herbicidal effect.
Second, choose the right weather and weather is important for the use of herbicides; low temperature and windy weather, is not conducive to the herbicide efficacy, only to apply during the winter, it is difficult to kill weeds, especially with isoproturon Herbicides, when used at low temperatures, may cause freezing damage to wheat seedlings. It should be applied to the time when the temperature of the sunny day is relatively high. At this time, the physiological metabolism of the weeds is relatively strong, which is beneficial to the conduction of the drug in the body, and the herbicidal effect is good.
Third, the addition of nitrogen fertilizer to improve the efficacy of the addition of nitrogen fertilizer can significantly improve the effectiveness of control. The mechanism of action is that urea and other fertilizers can reduce the tension and pH of the herbicide liquid surface and enhance adhesion.
I hope that Xiaobian's method can solve your problems and increase crop yield!
Cationic Fixing Agent is polyelectrolyte, consists of a series of organic synthesis with low molecular weight and strong cationic, which is generally 100% cationic. Product character is aqueous solution.
II. Performance Indicators:
1. Appearance: colorless to pale yellow viscous liquid
2. Solid content: â‰¥ 50%
3. PH: 2 ~ 6
4. Viscosity: 50 ~ 200 mpa.s
III. Application Field
Used in paper pulp as a cationic fixing agent. Usually the slurry contains colloidal particles consisted of fiber materials, additives and water, which are with anionic charge and interfere the papermaking process, so it is also known as anionic trash; the interference is mainly in the following aspects:
1. Influence wet chemical additives` normal function, especially for cationic retention and drainage aids, sizing agent; or cause to increase the amount of wet chemical additives;
2. Deposits in the paper machine system; interfere the efficient papermaking process.
3. COD discharge of sewage systems, increasing the load on the sewage treatment plant. Recommended for use in mechanical pulp, chemi-mechanical pulp, and secondary fiber pulp slurry and coating waste stuff. Anionic trash neutralized by fixing agent can be bonded to the fibers so as to be taken away by paper sheets.
IV. Methods of Application
Adding methods: excellent water-solubility; can spread out in water instantly. Dosing pump is generally used to drive it into a static mixer or a mixing pump , mixed with water, diluted to about 0.2% of the dissolved solution, and then into the slurry system.
Adding point: the general adding point is in the front of flow system, that is, before the machine chest or fan pump; or add in the pulp plant. Which is taken into consideration for the reaction time of the cationic fixing agent polymer molecules and garbage, also need to time and space for other wet end additives. According to the slurry source, sometimes you need to select two or more points to add. When the slurry contains a source of coated broke, generally requires additional anionic trash Fixative in the transport of the paper sheet.
Adding dosage: anionic trash content in the slurry is usually gauged by the cationic charge contents measured by PCD (particle charge analyzer) in the slurry. The measure will directly show the dosage tips, but the real dosage depends on the practical application. For general slurry, the recommend amount is in the range of 0.3kg ~1.8kg/t dry pulp.
V. Safe Operation
1. Cationic fixing agent is a water-soluble polymer, dissolved in water in a highly slippery state and avoid to spill on the floor. If spill, shall timely absorb with sand, sawdust.
2. Wear gloves, wear overalls to operate.
The product should be kept sealed, stored in cool, dry, ventilated places, and appropriate temperature should be 10-30 â„ƒ.
