Embodiment 1

[0028] Table 1 Indoor antibacterial test of prochloraz and Daobunling compound and single agent (rice blast fungus)

[0029] Drug name

[0030] The results of the indoor antibacterial test shown in Table 1 show that the co-toxicity coefficients of the mixtures of prochloraz and rice blastin constructed according to several ratios are all greater than 100, indicating that several ratios constructed have synergistic effects , but among several ratios, the co-toxicity coefficient of 1:3 is the largest. From the co-toxicity coefficient and economical considerations, it is recommended to select the weight ratio of prochloraz: blastilin as 1:3.

Embodiment 2

[0032] Table 2 Field disease control effect of 40% prochloraz·Daobunling EC at different concentrations

[0033] deal with

[0034] It can be seen from Table 2 that 40% prochloraz · Daobunling EC has a good control effect on rice blast, and with the increase of the dosage, the efficacy also increases.

Embodiment 3

[0036] Weigh 10.2 parts of prochloraz 98% of the original drug, 31.6 parts of the 95% rice blastling drug, add 10 parts of Nongru 600 (phenethylphenol polyoxyethylene ether), 50 parts of xylene, and add them together to the mixing kettle , stir until the original drug is completely dissolved, to obtain 40% prochloraz · rice blastin emulsifiable concentrate of the present invention.

Abstract

The invention discloses a sterilization compounded agent which comprises 5-25 portions of prochloraz and 20-40 portions of isoprothiolane by weight portion. The invention has the advantages that the sterilization compounded agent has favorable control effect to rice blast in a rice seedling stage and low cost of agricultural medicament, and can efficiently delay the occurrence of resistance; meanwhile, the prochloraz and the isoprothiolane are both low-toxicity pesticides, have no pollution to environment, and have obvious efficacy to rice sheath blight, rice false smut, as well as anthracnose, strip rust, root rot and powdery mildew of various vegetalbes, melons and fruits.

Description

technical field [0001] The invention relates to a pesticide preparation, in particular to a bactericidal compound suitable for rice to prevent and treat rice blast. Background technique [0002] Rice blast is a major disease that poses a great threat during seedling raising. This disease occurs in almost all rice-growing areas all over the world, and it is widely distributed. It is mostly caused by the infection of pathogenic fungi in the soil due to the influence of adverse environments. There are different degrees of occurrence every year. Mild occurrence causes the growth of seedlings to weaken and the roots to grow sluggishly. Severe occurrence of seedlings withers and turns yellow to death, resulting in insufficient seedlings, delaying farming time, and affecting rice production. [0003] In agriculture, the main medicaments currently used to prevent and control rice blast are single doses of prochloraz, rice blastin, and tricyclazole. The effect of the single agent fo...
