Embodiment 1

[0023] Embodiment 1: prepare medicament as follows

[0024] 10 parts Curvularia teff QZ2000, 15 parts Anthracnose Col-68, 20 parts Fusarium tansporum ZC201301, 7.5 parts sucrose, 15 parts soybean oil, 10 parts Tween, 15 parts 30% atrazine wettable powder , 15 parts of 10% refined fluazifop-methyl emulsifiable concentrate, 0.3 parts of sodium methylene dinaphthalene sulfonate, and 200 parts of bentonite.

[0025] The preparation steps are as follows:

[0026] (1) Preparation of the spore suspension of Fusarium pachytansporum: Inoculate the Fusarium pachytansporum ZC201301 strain on a PDA plate medium, culture it in the dark at 26°C for 8 days, and inoculate the meristems on the surface of the medium with sterile water. Wash the spores, centrifuge at 5000rpm for 10min to collect the spores, resuspend them with sterile water, and count to 5×10 8 / mL made conidia suspension;

[0027] (2) Preparation of spore suspension of Curvularia teffensis: inoculate Curvularia teffensis QZ2...

Embodiment 2

[0032] Embodiment 2: prepare the compound medicament of following composition (the concentration of sucrose, soybean powder, Tween is preferred):

[0033] 10 parts of Curvularia teff QZ2000, 15 parts of anthracnose Col-68, 20 parts of Fusarium tansporum ZC201301, 15 parts of 30% atrazine wettable powder, 15 parts of 10% refined fluazifop emulsifiable concentrate, sub 0.3 parts of sodium methyl dinaphthalene sulfonate, 200 parts of bentonite.

[0034] Set sucrose to set gradient: 5, 6, 7, 8, 9, 10 parts by weight;

[0035] Set the gradient of soybean oil: 10, 12, 14, 16, 18, 20 parts by weight;

[0036] Set Tween to set gradient: 5, 6.5, 8, 11.5, 13.5, 15 parts by weight;

[0037] The preparation method of the compound medicament is the same as in Example 1.

[0038] Comparing the effect of promoting the infection rate of crabgrass crabgrass in the compound medicament of comparative example 1 and embodiment 2:

[0039]Dilute the medicament prepared above with water at a rat...

Abstract

The invention discloses a compound improvement medicament for preventing common crabgrass herb, and a preparation method thereof. The medicament is prepared from eragrostis pilosa curvularia lunata, colletotrichum, fusarium pachytensis, saccharose, Twain, atrazine, fluazifop p butyl, a wetting agent and a dispersing agent according to a certain proportion. Through the combination of biological andchemical prevention medicaments, the common crabgrass herb in a paddy field can be efficiently inhibited or killed. According to the compound improvement medicament for preventing the common crabgrass herb provided the invention, multiple auxiliaries are adopted, so that a control effect of biological control bacteria is improved, the usage amount of a chemical pesticide is effectively reduced, the drug resistance of the common crabgrass herb is overcome, and the safety on paddy rice is high.

Description

technical field [0001] The invention relates to the field of agricultural science and technology, in particular to a compound improved medicament for preventing and treating crabgrass and a preparation method thereof. Background technique [0002] my country is the largest rice producing country in the world. Rice production has a long history and is widely distributed. The annual cultivation area is about 33 million hectares, and it is planted all over the country except Qinghai Province. Crabgrass crabgrass is a worldwide malignant weed, and it is also one of the most widely distributed and most harmful major rice field weeds in my country's rice fields. [0003] It is one of the 18 most widely distributed weeds in the world, and it is widely distributed in tropical and temperate regions. The ability to adapt to the environment is very strong, the growth period is relatively consistent with the crops, and it is easy to compete with the crops to consume soil fertility. Th...
