Embodiment 1

[0023] 1.5 kg of penoxsulam technical, 25 kg of cyclopentazone technical, 1 kg of sodium dodecylbenzene sulfonate, 8 kg of dispersant NNO, 4 kg of lauryl polyoxyethylene ether, 0.2 kg of ethylene glycol, 32.5 kg of kaolin, and 30 kg of light calcium were thrown into a mixer and mixed for 2 hours. The material fineness of 99% passes through a 325-mesh standard test sieve to obtain the wettable powder of the present invention.

Embodiment 2

[0025] 0.2 kg of penoxsulam technical, 2 kg of cyclopentazone technical, 1 kg of sodium dodecylbenzene sulfonate, 3 kg of sodium lignosulfonate, 2 kg of polyoxyethylene lauryl alcohol Ether and 91.8 kg of kaolin were thrown into the mixer together and mixed for 2 hours. The mixed material was added into the jet mill for pulverization. After pulverization, it was mixed for 2 hours through the mixer. The fineness of the mixed material was 99% and passed the 325-mesh standard Test sieve to obtain wettable powder. Then add the wettable powder and 20 kg of water into the kneader and knead to make a plastic material, and extrude the material into granules with a diameter of about 3 mm. After the granulation is completed, put it in an oven at 54 degrees to dry. Complete to obtain the granule herbicidal composition of the present invention.

Embodiment 3

[0027] 1.5 kg of penoxsulam technical, 28.5 kg of cyclopentazone technical, 1 kg of sodium dodecylbenzene sulfonate, 8 kg of dispersant powder, 2 kg of polyoxyethylene lauryl alcohol Ether, 2 kilograms of polyethylene glycols, 37 kilograms of kaolin, and 30 kilograms of light calcium were thrown into a mixer and mixed for 2 hours, and the mixed material was added into a jet mill for pulverization, and after pulverization, it was mixed for 2 hours through a mixer. The mixed material with a fineness of 99% passes through a 325-mesh standard test sieve to obtain a wettable powder. Then add the wettable powder and 18 kg of purified water into the kneader and knead at the same time to make a plastic material, and put the finished material into an extrusion granulator for granulation. The granulated product is placed in an oven at 54 degrees. After drying, the dried material is sieved with a standard test sieve of 10 mesh and 60 mesh, and the intermediate material is taken to obtain...

Abstract

The invention discloses a herbicidal composition for paddy fields and lotus root fields, which comprises two active ingredients of penoxsulam and penoxamazone, and the weight parts of penoxsulam and penoxamazone The number ratio is 1:6-1:25, and the weight percentage of the sum of the penoxsulam and cyclopentazone in the composition is 1-55%. The herbicide composition of the invention is convenient to use, low in cost, good in herbicide effect and ensures the safety of rice and lotus root growth.

Description

technical field [0001] The invention belongs to the field of agricultural plant protection, and in particular relates to a safe herbicide composition for paddy fields and lotus root fields. Background technique [0002] At present, chemical weeding is the main method used to control weeds in agriculture. In recent years, due to the large-scale use of some conventional herbicides for many years, many weeds have developed drug resistance and the control effect has declined. In paddy fields, the problem of weed resistance is more prominent, and the types of weeds are also more complex. A single herbicide will show some defects and limitations. Especially the lotus root field, there is no disclosed chemical agent for controlling weeds in the lotus root field so far. The main reason is because of the safety of herbicides on crops. The use of general herbicides will cause phytotoxicity to lotus roots, affecting growth and reducing production. [0003] Penoxsulam, English common...
