Embodiment 1

[0041] Evaluation of the ability of rice bran to suppress weeds in different rice varieties of Example 1

[0042] 1.1 Test materials

[0043] The rice bran materials used in the test included 4 categories of japonica rice, indica rice, hybrid rice and Yunnan local rice, a total of 30 species, and each material was specifically: japonica rice varieties (Yungeng 26, Yugeng 11, Yunjingyou 19, Yunjingyou 10 Yunjingyou 15, Yunguang 101, Chugeng 28, Yungeng 19, Chugeng 31, Yunguang 109, Yungeng 39, Fengdao 23); indica rice varieties (Yunguang 17, Yunliangyou 144, Yun You 948, Yunchao 7, Yiyou 673); hybrid rice varieties (Dianza 33, Dianza 31, Liangyou 1586, Dianza 35, Liangyou 2161, Liangyou 2111, Dianza 40, Dianza 37, Dianza Dianza 36, ​​Dianza 41, Dianza 46, Yuza 33) and Yunnan local rice variety Xiaomagu. The above rice materials are common in production and have been planted for a long time. All rice materials were purchased from the seed market in Kunming.

Embodiment 2

[0053] The influence of embodiment 2 processing method on the grass-suppressing ability of xiaomagu rice bran

[0054] The study in Example 1 shows that the water extract of the rice bran of Yunnan local rice variety Xiaomagu has a significantly greater inhibitory effect on the growth of barnyardgrass than other varieties, and its 5% water extract has an inhibitory effect of 17.86% on barnyard grass under indoor conditions. Existing studies have shown that husk ketone contained in rice husk is the main effective component of rice husk to play the role of inhibiting weeds. However, rice husk is rich in cellulose, lignin, silica and other substances, which are difficult to degrade, and the husk ketone contained in it is also difficult to release, which affects the weed suppression effect of rice husk. In this study, different processing methods of rice bran were compared to explore their effects on the ability of rice husk to inhibit weeds.

Embodiment 3

[0074] Example 3 Study on the optimal ratio of rice bran to butachlor synergistic effect

[0075] Butachlor has a good control effect on monocotyledonous weeds in rice seedling fields, direct seeding fields, and transplanting fields. It is widely used in modern agriculture to control weeds in rice fields. However, the butachlor currently used in the market is emulsifiable concentrate, and its carrier is xylene and various other organic solvents. The impact of long-term and large-scale use of herbicides and various organic solvents on environmental pollution and food safety has aroused widespread concern. The research in Example 2 shows that the pulverized rice bran of rice xiaomagu is fermented with Bacillus subtilis, Bacillus licheniformis and lactic acid bacteria for 48-72 hours, then evaporated to dryness under reduced pressure and low temperature, and its weed-inhibiting ability to barnyard grass is significantly improved. This study envisages using the fermented product ...

Abstract

The invention discloses a novel weeding composition for preventing and controlling weed in paddy fields and a preparation method thereof. The novel weeding composition takes a rice chaff processing product of paddy small asaya as a carrier and comprises butachlor, organic solvent and various pesticide auxiliaries. The novel weeding composition is prepared from, by mass, 98.357-99.485% of rice chaff processing product, 0.199-0.590% of butachlor, 0.149-0.492% of alkyl naphthalene sulfonate, 0.149-0.492% of alkyl naphthalene sulfonate formaldehyde condensate, 0.003-0.010% of acetone, 0.010-0.039% of xylene, 0.002-0.010% of glycerol and 0.003-0.010% of Tween-80. The novel weeding composition has the advantages of safety and high efficiency in preventing and controlling weed in the paddy fields, and field consumption of harmful chemicals like butachlor and xylene is lowered remarkably.

Description

technical field [0001] The invention belongs to the pesticide technical field of a herbicide for controlling weeds in paddy fields and a preparation method thereof. Specifically, the rice husk of the local rice variety Xiaomagu in Yunnan is processed through crushing, fermentation, and drying under reduced pressure, and then used as a carrier and mixed with butachlor, wetting agent, and dispersing agent in a certain mass ratio to obtain A new herbicidal composition that can be used to control weeds in paddy fields. Background technique [0002] Pesticides are an indispensable means of production for the prevention and control of agricultural pests. Modern agricultural production mainly controls the occurrence and harm of pests and diseases through chemical pesticides. The latest statistics show that about 320,000 tons of various chemical pesticides are used in my country every year, saving about 1 / 3 of the grain output. However, the long-term use of large quantities of che...
