First, the period of injection
It can be carried out in the growth period from the germination stage to the deciduous stage, and the best in the growth period from April to August. The specific injection time should be based on the growth history of the pests to prevent the best injection time. After the leaves are deciduous, they cannot be injected during the dormant period before germination.
Second, the choice of pesticides
A systemic strong agent such as 50% methamidophos EC, 40% omethoate EC, 75% wet carbofuran powder, 50% acaricidal emulsifiable concentrate, 50% monocrotophos emulsifiable concentrate can be used. Appropriate pesticides should be selected depending on the pest.
Third, the injection method
Use a woodworking drill with a diameter of 0.8 to 1 cm to drill a hole of 8 to 10 cm deep at a 45-degree angle on a trunk of 15 to 50 cm from the ground, reaching the core. The tree can be drilled 3 to 5 holes spirally around the trunk, the middle tree can be drilled 2 to 3, the small tree can be drilled 1 and the saw can be used to inject the liquid with an inhaler or syringe. If you are injecting a large area, you can use a perforated injection machine. The orifice should be sealed (can be sealed with wax seal, mud seal or tape). The injection hole can heal after two months.
Fourth, the amount of injection
According to the size of the tree, the amount of drug to be injected is calculated according to the original drug solution. Generally, the tree with a diameter of 15 cm or more is 6 to 10 ml per plant, and the medium tree with a diameter of 10 to 14 cm is injected 4 to 6 For milliliters, each strain with a dry diameter below 10 cm can be injected 2 to 4 ml.
Five, matters needing attention
1. When the temperature is not high, 1 to 2 times of the drug solution can be injected. When the temperature is high in summer, the original drug should be diluted 3 to 6 times and then injected, so as to avoid phytotoxicity caused by excessive concentration of the drug solution.
2. The tree species that are easy to flow glue should be drilled as much as possible, and the method of chemical liquid drying should be used for prevention and treatment.
3. According to the control object, the pesticide with the best systemic effect should be selected according to the control object, and only one pesticide should not be used.
4. Do not use tree-sensitive pesticides to avoid phytotoxicity.
The armature assembly or anchor system is the very important component of Solenoid Valve. An internal stainless steel plunger moves up and down to seal on the top and bottom valve seats. Brando provides armatures in multiple sizes depending on the application's flow requirement. Four common pneumatic functions are available which include:
1. 2/2 normally closed(NC),
2. 3/2 normally closed(NC),
3. 2/2 normally open(NO),
4. 3/2 normally open(NO).
The seals in the plunger are NBR (standard), but FKM, HNBR, PTFE, EPDM are available for different media and temperatures. Most of our armatures are designed to accept AC and DC voltages. Some armatures are DC only for low watt applications.
Brando offers flexibility as the connection to the seat cavity can be with a thread/o-ring seal style or o-ring flange style that requires a mounting plate.
Trunk injection should pay attention to the problem
The use of trunk drilling and injection to control pests is not only easy to operate, but also effective. Moreover, it can prevent and control pests such as beetles, geigers, etc. method. Based on the practice of prevention and control in the garden department of Linyi City, Shandong Province for several years, we will talk about several problems that should be paid attention to in the trunk injection.
