The damage is very serious. How should we use pesticides for the control of Chinese cabbage cabbage butterfly? China Pesticide Network Xiaobian for your analysis:
When the cabbage butterfly is young, apply 5 percent of the yinbao or the card gram, or the agricultural dream emulsifiable concentrate 2000-3000 times solution; 20 percent of the chlorpyrifos 500-1000 times solution, above The biological agents described are relatively slow due to their obvious effects:
For the cabbage butterfly we can choose to apply 50% phoxim emulsion or 80% dichlorvos emulsion, or 80% WP Bataan, or 2% Point 5 of the enemy killing emulsion or 10% Xingmianbao emulsion, or 2.5% of the chrysanthemum emulsion such as Kung Fu emulsion, 2000 to 3000 times liquid; 0.5% of the halogen The insecticidal emulsifiable concentrate is either a 1% matrine alcohol solution or a 0.5 to 0.5 percent solution of the cucurbitacin alcohol solution.
We need to pay attention to the control of cabbage butterfly:
First, the selection of chemical pesticides for prevention and treatment needs to be based on the local survey results at the time. It is forbidden to abuse pesticides and try to apply the pesticides at the younger age of the larvae. This can achieve twice the result with half the effort.

The masonry bit is a variation of the Twist Drill Bit, the bulk of the Tool is a relatively soft steel, and is machined with a mill rather than ground. An insert of tungsten carbide is brazed into the steel to provide the cutting edges.
Masonry bits typically are used with a Hammer Drill, which hammers the bit into the material being drilled as it rotates; the hammering breaks up the masonry at the Drill Bit tip, and the rotating flutes carry away the dust.
Hammer drill bits often use special shank shapes such as the SDS type, which allows the bit to slide within the chuck when hammering, without the whole heavy chuck executing the hammering motion.
Masonry bits of the style shown are commonly available in diameters from 3 mm to 40 mm. For larger diameters, core bits are used. Masonry bits up to 1,000 mm (39 in) long can be used with hand-portable power tools, and are very effective for installing wiring and plumbing in existing buildings.
