Problems solved by technology

[0004] However, there is no method for mitigating the phytotoxicity of herbicides to deciduous trees in the prior art. Can the method of mitigating the phytotoxicity of herbicides to crops such as rice, soybean, corn, and cotton be used to alleviate the phytotoxicity of herbicides to deciduous trees? Therefore, taking fomesafen as the experimental material, looking for a method to alleviate the damage of herbicides to some deciduous trees, it is helpful for solving specific problems in production practice, and for the construction of agricultural production and landscaping projects. , has a certain practical significance

Embodiment 1

[0042] Embodiment 1: get 0.8 gram of α-naphthalene acetic acid former powder, 0.8 gram of ferrous sulfate former powder, make small package medicament respectively, need to alleviate the application dose of fomesafen phytotoxicity field block as 667 square meters, for standby, When using, first take 4ml of absolute alcohol to dissolve the original powder of α-naphthaleneacetic acid, then take 4ml of water at about 60°C to dissolve ferrous sulfate, mix it with 40kg of neutral water with a pH value of 7.0-7.6 , ready-to-use, spray directly on the main pole, side branches, and roots of the arbor, and in case of continuous sunny days, water the whole body of the arbor every 3 days until it returns to normal.

Embodiment 2

[0043] Embodiment 2: get α-naphthalene acetic acid former powder 0.4 gram, ferrous sulfate former powder 0.4 gram, make small-packed medicament respectively, need to alleviate the application dose of fomesafen phytotoxicity field block as 667 square meters, for standby, When using, first take 4ml of absolute alcohol to dissolve the original powder of α-naphthaleneacetic acid, then take 4ml of water at about 60°C to dissolve ferrous sulfate, mix it with 40kg of neutral water with a pH value of 7.0-7.6 , ready-to-use, directly sprayed on the main pole, side branches and roots of trees.

Abstract

Belonging to the technical field of pesticide use, the invention discloses a method for relieving the phytotoxicity of fomesafen to part of deciduous trees. The method is characterized in that: a medicinal liquid composed of alpha-naphthylacetic acid, ferrous sulfate and water in a mass ratio of 0.8-1.2:0.8-1.2:40000-60000 is prepared, 38-42kg of the medicinal liquid is sprayed to lateral branches, trunks and roots of arbor for per 667 square meters, part of deciduous trees particularly refer to mulberry trees, hackberries, Koelreuteria paniculata, red maple trees, oriental cherry trees and crape myrtle trees, during preparation of the medicinal liquid, alpha-naphthylacetic acid is dissolved in 5-10 times of anhydrous alcohol, ferrous sulfate is dissolved with 5-10 times of warm water at atemperature of about 60DEG C, then water is added for dilution to reach a target concentration, the medicinal liquid is prepared for immediate use, and if continuous sunny days appear after treatmentby the medicinal liquid, clear water is sprayed to the lateral branches, trunks and roots of arbor once every three days until the trees return to normal.

Description

technical field [0001] The invention belongs to the technical field of pesticide use, and in particular relates to a method for alleviating the phytotoxicity of fomesafen on some deciduous trees. Background technique [0002] Herbicides have been widely used in agricultural production, and they have played an important role in reducing labor intensity and improving labor productivity. Regarding the use of herbicides for field crops, broad-leaved weeds are generally controlled by selective herbicides for the control of broad-leaved weeds in grass crops; selective herbicides for the control of grass weeds are used for broad-leaved crop fields. Poaceae weeds. The chemical name of fomesafen is 5-(2-chloro-α,α,α-trifluoro-p-tolyloxy)-N-methylsulfonyl-2-nitrobenzamide, which is a highly selective The post-emergence herbicide in soybean and peanut fields can effectively control broad-leaved weeds in soybean and peanut fields, and also has a certain control effect on grass weeds. ...
