Nicosulfuron injury remedies

Generally , the corn itself is strong resistance , nicosulfuron a slight phytotoxicity , without treatment, only temporarily inhibited growth of corn , can be restored after a period of time , does not affect the production.

If severe injury , need to be addressed , we can use the following measures:

Even detox in a smoke -ethyl injury has occurred or will occur , to take early measures to detox . On the initial injury on corn plants that can be used 3-5 times spray equipment wash water spray pesticide residues on plants .

2 strengthen field management ( 1 ) pouring enough water , prompting a lot of corn roots absorb water to reduce the concentration of the herbicide plant body , relieve injury.

( 2 ) appropriate to increase the depth and frequency of hoeing , enhance soil aeration , and promote beneficial soil microbial activity , accelerate the decomposition of soil nutrients , enhance maize root under water and nutrient absorption capacity, so as soon as possible to restore normal maize plants growth and development.

( 3 ) spraying large cloud -120 ( natural brassinolide ) diluted 1500 -fold or GA plus 1 % urea aqueous solution or spiritual harm , leaf treasure diluted 500 times in the morning or evening dew dry with low pressure sprayer to spray both sides of the blade , and promote normal growth of plants , in order to effectively reduce injury .

( 4 ) the injury occurred corn plots should be combined with water , increasing livestock manure composting facilities , ammonium bicarbonate , ammonium nitrate, urea and other fast-acting fertilizer to promote root development and regeneration , restoring victims corn physiology to reduce tobacco ethyl phytotoxicity to corn damage. But also foliar hand pump sprayers of 1% -2 % urea or 0.2 % -0.3 % potassium dihydrogen phosphate solution or Huimanfeng 60-800 times, resume normal growth favorable for corn .

Should also actively controlling other corn pests, in order to improve the ability of maize to resist injury . However, if the injury caused by the cornfields too heavy , these measures can not relieve victims extent, you can only take one or switching to other crops destroyed to avoid greater losses. Seven days before and after use can not be used organophosphate pesticides , dry weather , be sure to increase the amount of use , increased amount of detergent , washing powder is a good adhesion agent. First watering after application .
