Crop spraying pesticides, how to avoid and reduce phytotoxicity

The first is the correct selection of pesticides. When selecting a pesticide, it is necessary to understand its characteristics and strictly follow the scope of prevention and treatment indicated by the label. When purchasing, it is necessary to prevent counterfeit and shoddy products, and ask for purchase invoices or credit cards; the second is to look at the sky, see the ground, see the seedlings, avoid adverse weather, bad haze, sensitive crop varieties and drug use during the growth period; Scientific application of pesticides, strictly in accordance with the scope of control and dosage on the label. Do not arbitrarily expand the control of crops and increase the concentration. It is necessary to apply the drug evenly at one time, avoid repeated use of drugs, and do not mix pesticides in order to avoid the occurrence of phytotoxicity. Herbicides are different from pesticides. Herbicide use is slightly inappropriate, but it may lead to crop failure. For herbicides, “pharmaceutical effect” and “drug damage” are often only one step away. Therefore, it is especially cautious when selecting and using herbicides. It is necessary to master scientific methods to prevent herbicides from becoming "phytotoxic agents". When applying herbicides, especially broad-spectrum herbicides, the wind direction should be observed, and a windshield should be installed on the nozzle to avoid harming the crops of the adjacent field, and at the same time, the medicine should be thoroughly washed before it can be used to apply other pesticides. Take care to avoid the use of pesticides that have residual phytotoxicity to the crops.

Erlenmeyer Flasks

Erlenmeyer flasks are widely use in cell suspension culture, medium confifiguration, mixing and storage.It is suitable for culturing cell lines with high oxygen requirements. It can also be used to culture bacteria, fungi and animal and plant cells in suspension. Compared with culture flasks, dishes and spinner flasks, it requires less work and is an economical solution. Cell Culture tool ideal for media preparation, mixing and storage.Reduces the chance of experimental personnel being infected during bacterial culture work.
