The leaf miner belongs to the order Diptera, which is divided into many families and species. Hosts mainly include leaf raisins, melons and fruits, beans, etc. The main damages are: larvae are harmful to the leaves, and the loquat leaves the upper epidermis to form a tortuous tunnel, which affects the growth of vegetables. Generally, there are 1-2 head lice and worm feces in the leaf end, which causes the vegetable to lose the commodity value and edible value. The worm can develop on manure and humus when no suitable host is found. The prevention and control measures are: comprehensive use of agricultural technical measures, vigorous development of biological control technologies, scientific implementation of physical control measures, strict control of chemical control measures, implementation of pollution-free production technology operating procedures: Linyi Fertilizer Network Copyright

3. Because the leaf miner is in the larval stage, the medication must grasp the critical moment from the peak of spawning to the early stage of egg hatching. This period is also the period of the lowest resistance of pests. The commonly used agents are: sprayable 40% green vegetable treasure 1000 times liquid, or spray 21% killing emulsifiable milk 3000 times liquid. Follow the principle of pesticide use, select the correct variety of pesticides, and strictly prohibit the use of high-toxicity, high-residue pesticides, pesticide dosage, dilution factor, application method and safety interval to implement the “safety standards for pesticide use†issued by the Environmental Protection Bureau.

Diameter Tape Measure
Basically there are two types of Diameter Tape Measure, one is Pipe OD Tape Measure Diameter Circumference, another is ID (Inner Diameter) PP Tape Measure
Pipe OD Tape Measure Diameter Circumference
Product Description:
The 2-meter Pipe OD Tape Measure Diameter Circumference is made of reliable material to satisfy precise diameter measuring requirement.The reading for the perimeter, accurate to 1 mm. The tape is double sided with circumference (measures in cm & inch) and diameter (measures in inch & inch) on the either part. Pipe od tape measure adopts fiberglass tape to deliver water and stain proof effect and to ensure that it is of good elasticity for diameter measuring. The retracting mechanism is built in the durable ABS case, thus service life is extended. Wintape provides the diameter tape measure with other patterns and offers customized logo for you.
ID (Inner Diameter) PP Tape Measure
Product Description:
Inner diameter tape measure is made of PP material that is of excellent stress tensile strength and high elasticity. The scale numbers are already been calculated so the tape gives you the result directly without calculating. The practical ID measuring tape can be adopted in various ways such as pipe and container measuring. The double sided inner diameter measuring tape makes number reading easier and more convenient.
