The Comparison of Four Pesticides and Which One Is Better？(二)

The comparison of effective period

Chlorfenapyr: It has no effect on eggs but has a prominent effect on the control of adults with a duration of 7-10 days.

Indoxacarb: It also has no effect on eggs but can kill lepidoptera pests both in big and small size with a duration of 12-15days.

Tebufenozide: It has the good egg-killing ability.The pests will be in a state of chemical sterilization after feeding.The effective period is about 15-30 days.

Lufenuron: It has a strong egg killing effect with a relatively long duration,up to 25 days.

The effective period ：Lufenuron＞Tebufenozide＞Indoxacarb＞Chlorfenapyr

The comparison of safety

Lufenuron：It has no pesticide damage from present market feedback information.

Chlorfenapyr: It is only sensitive to cruciferous vegetable and melons from present market feedback information and has certain security risk if it is used in high temperature or high dose.

Indoxacarb：It has high safety and no pesticide damage.

Tebufenozide：It has high safety and no pesticide damage, and can cause chemical sterilization of some lepidopteran pests after use. There will be a second insect death period after 10 days.

Safety：Tebufenozide＞Indoxacarb＞lufenuron＞Chlorfenapyr

Of course, the combinations of different products are designed to achieve different purposes.The better formula is chlorfenapyr+lufenuron which can perfectly combine their quick action and long duration so as to really achieve the ultimate goal of saving labor, saving time and saving money for farmers.

Due to the frequent use or high doses of pesticides ,pests will quickly produce resistance.we should still abide by the principle of "prevention first, comprehensive control". We should not only do a good job in drug rotation, delaying the emergence of resistance, but also choose to apply pesticides in the early age of pest,which can make the killing effect more prominent.

In a word, it is difficult to distinguish which one is better, because each insecticide has its own advantages. When choose pesticides,it is necessary to choose the most appropriate one according to the situation and the resistance of insect pests.
