Embodiment 1

[0029] The 5wt% chitosan oligosaccharide solution is diluted with water to the corresponding application concentration respectively, and the concentration is calculated according to the weight percent concentration, and is calculated in ppm (parts per million) concentration in the result record, and 50ppm represents the weight percent in the result record below The concentration is 0.005%. Water treatment was used as a control. The diluted solution is used to process pepper seeds and pepper plants in stages according to requirements, and the seed treatment is seed soaking, and the soaking time is 24 hours. The treatment mode of other stages is spraying treatment of chitosan oligosaccharide aqueous solution, and the interval time of spraying treatment is 15 days. Each treatment is observed and detected through 3 test fields (667 square meters). The samples of the treated seeds are counted when the crops grow into 4 leaves after germination, and the statistics of the treatments...

Abstract

The invention relates to a chitooligo saccharide composiation used for resisting a pepper virus disease and an application and method thereof, and particularly relates to a pesticide composition used for resisting the pepper virus disease. The pesticide composition comprises the chitooligo saccharide, wherein the chitooligo saccharide is 0.005%-0.025% of the pesticide composition in percentage by weight. The invention also provides an application of the pesticide composition containing the chitooligo saccharide used for preventing the pepper virus disease, the application is characterized in that the chitooligo saccharide is 0.005-0.025% of the pesticide composition containing the chitooligo saccharide by weight. The composition provided by the invention solves an important problem of resisting pepper virus disease, in particular the pesticide composition comprising the chitooligo saccharide is used for processing seeds and plants of pepper so as to not only resist the pepper virus disease but also generate no phytotoxicity on crops, thereby having no pesticide residue.

Description

technical field [0001] The invention belongs to the field of agricultural chemistry, and in particular relates to a control composition and a control method for pepper virus disease, in particular to a chitosan oligosaccharide composition for resisting pepper virus disease and its use and method. Background technique [0002] Pepper (Piper nigrum Linn.) is a tropical evergreen climbing plant and an important tropical spice plant. Regardless of planting scale, output and value, it ranks first among all spices, and is called the "king of spices" and "Ugin". In the world, except pepper blast (also known as root rot (foot rot), Phytophthora foot rot (Phytophthora foot rot), quick wilt (quick wilt), quick death (sudden death), the pathogen is soil Phytophthora capsici) and pepper slow wilt (also known as (slow) chronic debilitation or decline disease (slow decline), or pepper yellows (pepper yellows), the pathogen is borer nematode (Radopholus similis), root-knot nematode (Melo...
