Second, the application of tea for export products in our province
Our province is a big tea producing province. Because of the heavier pests on tea trees, the amount of medicine used is larger. In recent years, the problem of pesticide residues has been plaguing the province's tea exports, resulting in a sharp decline in tea prices, seriously affecting the enthusiasm of tea farmers in our province. The use of low-toxic, low-residue pesticides to control tea tree pests and diseases is one of the key measures to solve this problem.
Uranus is a very comprehensive and excellent insecticidal and acaricidal agent for controlling pests on tea. In the EU pesticide residue testing program, its maximum allowable residue limit is 5.00 mg/kg, while cypermethrin allows Limited to 0.02 mg / kg, so Uranus is used at the correct dose without worrying about residual problems.
Third, the application of pesticides on field crops
On the corn, Anlubao and Green Pepsi can be used instead of methamidophos, hydroamine phosphorus, etc. to control underground pests such as tigers in the seedling stage. It can be used to control armyworms and cockroaches in the middle and later stages. On the rapeseed, Anjingbao and Green Pepsi can also be used to control the cabbage worms, and the aphids can be controlled by using imidacloprid. Wheat can be used to control aphids in the early stage.
The auger bit adds a long deep spiral flute for effective chip removal.
Two styles of auger bit are commonly used in hand braces: the Jennings or Jennings-pattern bit has a self-feeding screw tip, two spurs and two radial cutting edges. This bit has a double flute starting from the cutting edges, and extending several inches up the shank of the bit, for waste removal.
The Irwin or solid-center auger bit is similar, the only difference being that one of the cutting edges has only a "vestigal flute" supporting it, which extends only about 1â„2 in (13 mm) up the shank before ending.
The diameter of auger bits for hand braces is commonly expressed by a single number, indicating the size in 16ths of an inch. For example, #4 is 4/16 or 1/4 in (6 mm), #6 is 6/16 or 3/8 in (9 mm), #9 is 9/16 in (14 mm), and #16 is 16/16 or 1 in (25 mm). Sets commonly consist of #4-16 or #4-10 bits.
