Five alternative pesticides that ban pesticides

For a long time, five kinds of highly toxic and high-residue pesticides such as methamidophos used by vegetable farmers have been banned in the technical regulations for the production of pollution-free vegetables. Here are five alternative pesticides that are banned, which can achieve the same control effect.
1. Methamidophos is a broad-spectrum insecticide. It used to be used to kill all kinds of pests, but its high toxicity, residual period of more than 30 days, often causing poisoning incidents of humans and animals, is the first banned pesticide production in pollution-free vegetables. .
For lepidopteran pests such as Pieris rapae, Plutella xylostella, and pea pods, there are two types of alternative pesticides: one-time biological pesticides, such as moth sorghum, century lore, peach xiaoling, agricultural land, etc.; second, the use of compound pesticides Common mixes are dichlorvos + BT, dichlorvos + kung fu, etc. Should pay attention to the use: 1, in the low-age spraying of pests, the effect is good; 2, the use of various pesticides , the use of biological pesticides, in order to avoid the emergence of resistance to pests; 3, now more pesticides have contact, should choose The best effect of spraying insects during the feeding period is that the multi-pea pods crawl out of the pods for food at 6:00~8:00 in the morning, and the spraying effect is best.
For the migratory pests such as yellow scoop and yellow squash, there are dichlorvos, agricultural land, phoxim and so on. In use, it should be noted that: 1. The large-area simultaneous control effect is good; 2. When the number of yellow scoops is large, in addition to the spray control, the underground larvae should be killed by root irrigation; 3. The interval is 5 days to 7 days, continuous prevention 2 times ~ 3 times.
Aphids, whitefly mites are easier to kill, and can be controlled in time with phlegm and dichlorvos.
Second, dicofol was previously used to kill red spiders, mites and so on. The alternative pesticides are insects, worms, worms, etc., and the effect is obvious after use.
Third, omethoate was mainly used to kill melons such as thrips, and alternative pesticides include puff and dimethoate.
4. Carbofuran was previously mainly applied to the soil to kill nematodes and other soil pests. Alternative pesticides include Miller and Dixon. In addition, the same effect can be achieved by using the method of turning the soil and applying lime.
V. Methyl 1605 has been widely used to kill various vegetable pests, such as twill moth, alternative pesticides and methods of use similar to methamidophos.
Vegetable production should strictly abide by pollution-free operating procedures, ban high-toxic, high-residue pesticides, and must strictly comply with the safety period for pesticides that are allowed to be used. By increasing the level of application, it not only meets the requirements of pollution-free vegetables, but also achieves the goal of high yield and quality.

Liquid Reservoir

4 Channel Reagent Reservoirs,8 Channel Reagent Reservoirs,12 Channel Reagent Reservoirs,96 Well Reservoir,384 Well Reservoir, from Yongyue Medical, is made of strong clear polypropylene (PP). Low profile designation which is suitable for small volume robotic tips used in high flux instruments. In the automatic pipetting process, the reservoir can perfectly overcome the surface tension of the liquid and minimize residual liquid

Our Reservoir Plates are perfect for storing volumes of samples to be pipetted into other microplates for further applications.
These plates are manufactured in cleanroom facilities which are certified free of RNase, DNase, human genomic DNA and endotoxins. We use only the highest medical grade virgin polypropylene with high resistance against chemicals such as DMSO, phenol, and chloroform. Pyramid channel bases are best for small volume recovery. The standard SBS footprint ensures its compatibility with automation.
Our sturdy and reusable reagent reservoirs can stand-up to autoclaving, exposure to temperature extremes, and chemicals. Made from polypropylene these reservoirs offer a stable base that makes them suitable for manual procedures as-well-as automation.
These fully automation compatible reservoirs feature an SBS footprint and can be used in plate handlers or stackers. To minimize space on platforms (when a stacker is not in use) or under hoods, these reservoirs can be filled and stacked.
