[0002] Although there are various control measures for pests in current agriculture, new and more effective and reasonable compounds for killing pests are still being continuously explored and discovered. The present invention provides a new type of compound that can be further studied. Spirocyclic compounds have stood out among many pesticides due to their unique chemical structures, novel modes of action, excellent control effects, and low resistance development, and have become a hot topic in current pesticide development. Due to the frequent use of single pesticides, insects or weeds have developed resistance to existing pesticides, reducing the control effect of pesticides. In the field of plant protection, spirocyclic compounds have shown broad application and development prospects and can solve the increasingly serious problems of pesticide resistance. Therefore, spirocyclic compounds have opened up new horizons for the development of pesticide chemistry and provided new ways to find new pesticides with high efficiency and low toxicity.

[0183] 3.4. Activity Tests on *Amaranthus retroflexus* and *Eclipta prostrata*
[0184] Pot experiment method: The target weeds for testing were *Amaranthus retroflexus* and *Eclipta prostrata*. Take flowerpots with an inner diameter of 7.5 cm, fill them with a composite soil (vegetable garden soil: seedling substrate, 1:2, v / v) to 3 / 4 of the pot, directly sow the above two weed targets (germination rate ≥ 85%), cover with 0.2 cm of soil, and wait until the weeds grow to about the three-leaf stage for standby. After applying each compound at a dose of 200 g a.i. / ha in an automatic spray tower (model: 3WPSH 700E), move the weeds into the greenhouse for cultivation after the liquid medicine on the leaf surface has dried. Investigate the activity (%) of the weeds 30 days later.
