Abstract

The invention discloses a resistance inducer for inducing wheat to resist gibberellic disease. The resistance inducer for inducing wheat to resist gibberellic disease comprises sodium nitroprusside, salicylic acid, oligochitosan and potassium iodide. Every 100 ml of resistance inducer comprises, by weight parts, 0.75-1.5 g of sodium nitroprusside with a mass concentration of 99.5%, 3-7.5 g of salicylic acid with a mass concentration of 99.5%, 1.5-3 g of oligochitosan with a mass concentration of 95% and 1.0-1.5 g of potassium iodide with a mass concentration of 99.9%. The salicylic acid is dissolved through ethanol, and other ingredients are dissolved through water. The resistance inducer is sprayed on wheat blades during a wheat ear period; after being absorbed by the blades, the resistance inducer activates active substances and enzymes in the wheat to resist infection of gibberella saubinetii and inhibit scab extension, gibberellic disease occurrence and harm are prevented and reduced.

Description

technical field [0001] The invention relates to an inducer, in particular to an inducer for inducing wheat to resist scab infection, to induce wheat to resist scab infection, and to prevent and reduce the occurrence of scab. Background technique [0002] After wheat heading, it often encounters continuous rainy, humid and dewy, sultry climatic conditions, and scab will be prevalent in a large area, causing disasters in a short period of time. [0003] Fusarium scab is one of the main diseases threatening wheat production, and it occurs all over the world. my country is the most harmful country of wheat scab in the world, with an annual damage area of ​​about 7.5 million ha 2 , accounting for 1 / 4 of the national wheat area, resulting in a yield loss of 2-3 million tons (Simpson D R, Weston G E, Turner J A, et al . Differential control of head blight pathogens of wheat by fungicides and consequences formycotoxin contamination of grain. European Journal of Plant Pathology, 20...
