Embodiment 1

[0026] The plant seed inhibitor treatment of test design is glyphosate alone, can adopt existing method to add auxiliary agent and water known to those skilled in the art to make water preparation, get 490 grams of glyphosate potassium salt, add auxiliary agent about 100 (40 grams of sodium α-alkenyl sulfonate, 55 grams of alkyl glycosides, 5 grams of tea saponin and a small amount of antifoaming agent), prepared with water into 1 liter of liquid medicine, without adding or adding urea 5g\sucrose 25g (1L medicine Add 30g of nutritional ingredients in urea, the weight ratio of urea to sucrose is 1:5), urea 25g\sucrose 75g, urea 50g\sucrose 125g / liter, dissolve in 1000 liters of tap water, and differentiate the flower buds of Eupatorium adenophorum planted in pots Period, use the above 4 different proportions, spray treatment with 0.5% (5g glyphosate in 1L medicament) and 0.08% (0.8g glyphosate in 1L medicament) concentration, set 4 repetitions, spray When using a sprayer, press...

Embodiment 2

[0030] The plant seed inhibitor treatment of test design is that glyphosate is used alone, gets 490 grams of glyphosate potassium salts, adds about 100 grams of additives (40 grams of alpha-alkenyl sulfonate sodium, 55 grams of alkyl glycosides, tea saponin 5 g and a small amount of defoamer), prepared with water into 1 liter of liquid medicine, without or adding 15 g of ammonium bicarbonate\25 g of sucrose, 25 g of ammonium bicarbonate\75 g of sucrose, 50 g of ammonium bicarbonate\125 g of sucrose / liter, dissolved in 1000 1 liter of tap water, in the flower bud differentiation stage of Eupatorium adenophorum planted in pots, use the above 4 different proportions to spray with 0.5% and 0.08% concentrations respectively, set up 4 repetitions, use a sprayer when spraying, and use 80ml / m 2 spray. When the fruit is ripe and the pappus will unfold, harvest 10 achenes of the capitulum from each plant respectively, and the full achenes are counted as fruiting seeds, and the seed se...

Embodiment 3

[0034] The plant seed inhibitors in the experimental design were treated with glyphosate alone and with ethephon at a weight ratio of 20:1, 10:1, 5:1 and 4:1. Take 490 grams of glyphosate potassium salt Or the compound composition of glyphosate potassium salt and ethephon in proportion, add about 100 grams of additives (40 grams of α-alkenyl sulfonate sodium, 55 grams of alkyl glycosides, 5 grams of tea saponin and a small amount of defoamer ), was prepared into 1 liter of medicinal solution, added urea 25g\sucrose 75g (1L medicament was added with 100g nutrients, and the weight ratio of urea to sucrose was 1:3), dissolved in 1000 liters of tap water, and planted in pots and pots. During the flower bud differentiation stage of Eupatorium, use the above 4 different proportions to spray with 0.1% concentration, set up 4 repetitions, use a sprayer when spraying, and use 80ml / m 2 spray. When the fruit is ripe and the pappus will unfold, harvest 10 achenes of the capitulum from ea...

Abstract

The invention discloses a plant seed development inhibitor for control over weeds and application thereof. The plant seed development inhibitor is prepared from a plant growth regulator and water; the main ingredient of the plant growth regulator is glyphosate. The plant seed development inhibitor is further prepared from at least one of nutritional ingredients and an adhesive; preferably, the plant seed development inhibitor is further prepared from nutritional ingredients and an adhesive. The plant seed development inhibitor inhibits flower bud differentiation and seed formation to eradicate seed generation and spreading, and the technology for control over weeds is realized. The screened-out plant seed development inhibitor is low in use concentration and safe to the environment. At present, no report about research on Eupatorium adenophora seed inhibitors exists at home and abroad, and research on the aspect will provide a new way for preventing invasion of the weed and controlling the weed.

Description

technical field [0001] The invention relates to a plant seed growth inhibitor for preventing and controlling weeds and an application thereof, which belongs to the technical field of weed control in the subject of plant protection. Background technique [0002] Since the birth of the first selective herbicide 2.4-D in the 1940s, the use of chemical herbicides has brought many benefits to farmers and agricultural production, and with the advancement of science and technology, new varieties of herbicides have been continuously developed. The proportion of pesticides is increasing. However, while chemical herbicides bring benefits, they also bring serious negative effects such as environmental safety, weed resistance, chemical residues and so on. Therefore, seeking low dosage and high efficacy herbicides has become the focus of this field. Glyphosate is a broad-spectrum destructive and non-selective herbicide, which has extremely low toxicity to the environment, is easy to de...
