Comparison of repellent mesh bags and paper bags Repellent mesh bagsPaper bags Good ventilation and pervious to sunlight. Poor ventilation and light transmit. No heat accumulated problem. Poor heat dissipation. Don’t keep rain and repellent won’t be flushed off. Repellent mixed in side plastic. Easy broken in the raining and has rain accumulation problem. Mesh designed without heat pile up. Make fruits grow in nature. Water proof paper become worse ventilation and light transmit. Easy observe fruits growth and maturity for harvest. Can’t observe fruits growth and maturity. Excellent photosynthesis increase fruits sugar content ( ∘ brix) and flavor. Poor photosynthesis cause lower sugar content( ∘ brix) and lesser flavor. After bagging fruits growth hasn't dormancy. About two weeks dormancy occur after bagging. Can be used repeatedly to save cost. Only one time used.

The difference between repellent and conventional mesh bags. Repellent mesh bags contain by repellent agent. Conventional mesh bags hasn’t repellent agent.

Recommendations Mesh bags keep fruits in nature color. Light color fruits such as: loquat,we strongly suggest don’t use. Fruits on orchid side, please keep leaves as shelter to prevent from sun burn problem. Repellent mesh bags are mainly for fruits fly but not for all insects. Validity is till the bags fade into different color. Sterilization is strongly suggested for repeated use.
