Abstract:

The aim of this study was to evaluate the effect of 90% acetochlor EC on weeds in the spring and autumn peanuts field. The peanut safety and control efficacy of the weeds with 90% acetochlor EC was researched in South China. The results showed that, the control effect was up 80% 45 DAT on Eleusine indica (L.) Gaertn, Digitaria sanguinalis (L.) Scop, Echinochloa crusgalli with spraying 1080-1350 g(a.i.)/hm2 90% acetochlor EC before seedling emergence and after sowing of peanut, but it had a bad effect on Chenopodium serotinum L., Stellaria media (L.) Cry. in spring peanut field. So it provided the theoretical basis of 90% acetochlor EC on the weed control in South China spring and autumn peanuts field and was safety on peanut with recommended dose.
