What pesticide is most effective for eliminating red spiders
Today, the editor will explain some knowledge about the floral clinic, what pesticide is most effective for eliminating red spiders. Let's learn about it together.
Spring is always the peak season for red spider outbreaks. Many新手 gardeners don't know how to deal with such tenacious red spiders and are particularly curious about what pesticide is most effective. Below, I will introduce several pesticides, hoping they will be helpful to everyone!
Red spiders (Tetranychus cinnabarinus) and yellow spiders (Tetranychus urticae) can almost harm every kind of flower and fruit tree we plant. Mites are particularly fond of plants, and once they get attached to them, coupled with hot weather, basically no plant has any chance of surviving, being overwhelmed by such tiny formidable opponents. The drug resistance and resistance of mites are astonishing. Many drugs can kill some but not all, can kill larvae but not adults, and can kill both larvae and adults but not eggs. The tenacity and persistence of the mite family in damaging roses and monthly roses make people hate, feel helpless, and yet somewhat moved.
Cremon,螨危, Jinmanzhi, pymetrozine, Aikachan, have all been tried for a year. I will summarize the pros and cons.
Killing red spiders requires a pesticide that can kill both the insects and their eggs. It should be sprayed on both sides of the leaves, the potting soil, and around the pot, leaving no dead corners. Egg-killing drugs such as 螨危 and pymetrozine are both effective. Jinmanzhi and Aikachan are good for killing insects. Cremon is not recommended because it can burn the leaves of succulents, hydrangeas, and roses...
Jinmanzhi or Aikachan mixed with 调螨威 or pymetrozine, at a concentration of 3,000 times, applied every 3 days for 3-4 consecutive times, and preventively applied once a month, works well. Everyone can try this.
For red spiders, a pesticide that kills both the insects and their eggs must be used together. Red spider eggs reproduce every 3 days, which is why the pesticide should be sprayed every 3 days. Using a flower sprayer to spray water may wash them away temporarily, but there will be more by the end of the day. Let me introduce the effects of various pesticides to you!
Cremon, Jinmanzhi, and Aikachan are very effective in killing adult red spiders, while 螨威 and pymetrozine are good for killing eggs. In summary, both insecticides and egg-killing drugs must be mixed. And everyone should make sure to spray both sides of the leaves when applying pesticides.
