The appropriate period of application of crop pests and diseases generally refers to the period when pests and diseases are the weakest and the most sensitive to pesticides during the entire growth period. At this time, the use of pesticides for prevention and control can yield a multiplier effect. Different pests and diseases have different control periods. The determination of the appropriate period of application should generally follow the following principles:
The weakest link in the pest activity The pesticide is generally young, has weak resistance to pesticides, and has many fatal weaknesses in the living habits of pests and diseases. These are favorable times for pesticide application. In the 10 to 12 days after the larvae were hatched, the pests were not disperse when they were harmed. In addition, pests are generally the best time to use a medicine for prevention and treatment before the third instar.
Application of pesticides at the initial stage of pests and diseases According to the prediction of agricultural pests and diseases that may occur over a large area, the spraying of pesticides should be controlled during the favorable period of the occurrence of pests, so that pests and diseases can be easily controlled.
In different crops during the growing period, the resistance of the pesticide-resistant crops with different crop resistance is different. In general, the seed has the strongest drug resistance. Generally, the crops are not very resistant to adverse environmental conditions in the seedlings, flowering, filling and fruit tree germination, flowering, and other reproductive periods, and are prone to phytotoxicity. This period should be as short as possible. Apply less or reduce the application concentration.
Hydrophobic Interaction Chromatography Resins
UniHR Butyl and UniHR Phenyl are the two major classes of NanoMicro`s HIC resin products. Their supports are highly crosslinked polymethacrylate beads of uniformed particle size and open pore structure. Through proprietary surface hydrophilization and HIC ligand coupling chemistries, these resins are enabled with low non-specific adsorption property. UniHR Butyl and UniHR Phenyl HIC resins have been used by many biopharmaceutical customers for varied application.
