Glyphosate and sethoxydim phytotoxicity pyridine

Glyphosate ( Roundup )

( A ) the cause of the injury . With herbicides stem, leaf processing , corn sensitive to glyphosate , facilities or liquid fall into the mistake of corn plants will produce injury.

( Two ) phytotoxicity symptoms. With herbicides stems, leaves treatment , injury symptoms appear slowly, the drug leaves first appear water-soaked , leaf curl inward , growth was seriously inhibited. Tip , leaf margin wilting , and some plant whole plant slowly withered.

( Three ) injury prevention and mitigation measures . Facilities and to avoid misuse of liquid falling into cornfield. Since the injury develops slowly , need tens of days to be observed Simiao . Therefore , the occurrence of the injury as soon as possible under the circumstances may a drug measures . If the amount of pesticide per hectare more than 600 grams , garden hand sprayers you should consider destroying species .

Sethoxydim pyridine ( Arrest net )

( A ) the cause of the injury . With herbicides stem, leaf processing , corn sethoxydim pyridine sensitive , mistakenly applied or adjacent land administration sethoxydim pyridine , droplet falling into corn plants can produce injury.

( Two ) phytotoxicity symptoms. With herbicides stems, leaves treatment, contact with the liquid leaves produce chlorotic spots, chlorotic new leaves start from the base , and gradually extended to the entire leaf , leaves become yellow , brown or purple , and gradually dry up . Severe growth point wither , whole plant death , inhibited the growth of light .

( Three ) injury prevention and mitigation measures . Sethoxydim pyridine can not be used cornfield. Neighboring plots applied sethoxydim pyridine should allow sufficient isolation belt, pay attention to wind direction and speed when spraying , to prevent the liquid float moves cornfield. Once mistakenly water power sprayer sprayed serious harm , or damage should be promptly replant seed .
