How to prevent honeysuckle pests
The main insect pests of honeysuckle are aphids. Under high-temperature and rainy conditions, new leaves and rattan shoots are often harmed, and curling occurs, affecting growth. It is usually sprayed with 40% dimethoate emulsion 3000 times solution or 25% imidothiophosphate emulsion 1000 times solution. In addition, there are two easy ways:
1 Soak the cigarettes with 5 grams of water at a ratio of 70-80 ml and soak for 24 hours. After a little rubbing, filter the residue with gauze and spray it.
2 Use 1:200-fold detergent powder (soap water) to add a few drops of vegetable oil (not using oyster sauce) to improve efficacy. Stir thoroughly until the surface is not oily. Spray with a sprayer, or mix A little ginger water spray, the effect is also very good.
The “Come-too†net sold in the flower and wood shop sells 200 milliliters of water per packet and can be effective 20 to 30 minutes after spraying.
A vortex mixer, or vortexer, is a simple device used commonly in laboratories to mix small vials of liquid. It consists of an electric motor with the drive shaft oriented vertically and attached to a cupped rubber piece mounted slightly off-center. As the motor runs the rubber piece oscillates rapidly in a circular motion. When a test tube or other appropriate container is pressed into the rubber cup (or touched to its edge) the motion is transmitted to the liquid inside and a vortex is created. Most vortex mixers are designed with 2 or 4-plate formats, have variable speed settings ranging from 100 to 3,200 rpm, and can be set to run continuously, or to run only when downward pressure is applied to the rubber piece.
Vortex mixers are quite commonplace in bioscience laboratories. In cell culture and microbiology laboratories they may be used to suspend cells. In a biochemical or analytical laboratory they may be used to mix the reagents of an assay or to mix an experimental sample and a dilutant.
