Embodiment 1

[0043] Weigh the raw material (kg) according to the following mass:

[0044] Oxyfluorfen 8, Azone 2, Methanol 20, Phenylphenol Polyoxyethylene Ether Formaldehyde Condensate 14, Calcium Dodecyl Benzene Sulfonate 15, Water 41.

[0045] Preparation:

[0046] Mix 8 kg of oxyfluorfen, 2 kg of azone, 20 kg of methanol, 14 kg of phenethylphenol polyoxyethylene ether formaldehyde condensate and 15 kg of calcium dodecylbenzenesulfonate, stir well, and finally add 41 kg of water high shear, made of microemulsion.

[0047] The first active ingredient 5-10%, azone 1-3%, methanol 18-22%, phenethylphenol polyoxyethylene ether formaldehyde condensate 12-16%, calcium dodecylbenzenesulfonate 10-20% , the rest is water;

[0048] It is also possible to replace the microemulsion with new dosage forms such as water emulsion, aqueous suspension, wettable powder, and soluble powder.

Embodiment 2

[0050] Weigh the raw material (kg) according to the following mass:

[0051] Ethoxyfluorfen 5, Fomesafen 2.5, Azone 3, Methanol 18, Phenylphenol Polyoxyethylene Ether Formaldehyde Condensate 16, Calcium Dodecyl Benzene Sulfonate 10, Water 45.5.

[0052] The preparation method is as in Example 1.

Embodiment 3

[0054] Weigh the raw material (kg) according to the following mass:

[0055] 15 kg of fenben, 1 kg of fomesafen, 2 kg of azone, 5 kg of sodium naphthalenesulfonic acid formaldehyde condensate, 2 kg of phenylethylphenol polyoxyethylene ether formaldehyde condensate, 3 kg of sodium lignosulfonate, 4 kg of ethylene glycol, 0.1 kg of sodium benzoate, 0.2 kg of silicone defoamer, and 67.7 kg of water.

[0056] Preparation:

[0057] 15 kg of fenben, 1 kg of fomesafen, 2 kg of azone, 5 kg of naphthalenesulfonate formaldehyde condensate sodium salt, 2 kg of phenethylphenol polyoxyethylene ether formaldehyde condensate, 3 kg of sodium lignosulfonate , 4 kilograms of ethylene glycol, 0.1 kilogram of sodium benzoate, 0.2 kilogram of organosilicon defoamer, 67.7 kilograms of water mix uniformly, and through colloid mill, sand mill, make aqueous suspension.

Abstract

The invention discloses diphenylether pesticide compositions and use thereof. The diphenylether pesticide compositions comprise at least one of nitrofen, oxyfluorfen, fomesafen and acifluorfen or lactofen as an active component, and are used for controlling and killing shoots of citrus crops, wherein the content of the active component in percentage by weight is 0.1% to 90%. The diphenylether pesticides can be used for controlling and killing the shoots of the citrus crops grown for competing for nutrients with fruit when the fruit is produced in summer; therefore, the production cost is greatly reduced, and the fruit yield is improved; moreover, the diphenylether pesticide compositions have the advantages of being safe, efficient and economic, and controlling and killing the shoots of the citrus crops in summer.

Description

technical field [0001] The invention relates to a new application of pesticides, and specifically discloses a new application of a diphenyl ether pesticide composition for controlling and killing young shoots of citrus crops and the composition thereof. Background technique [0002] Citrus crops such as the southern characteristic fruit, the summer shoots that grow from April to July every year, compete with the fruit for nutrients. If not removed in time, it is easy to cause a large number of fruit drop. Production requires that it must be removed in time to ensure the normal growth of the fruit. . [0003] At present, the method of removing summer shoots in production is mainly based on manual picking, which not only consumes a lot of labor, but also often causes a large amount of fruit drop because large-scale planting cannot be removed in time. [0004] In the prior art, there is no safe, efficient and economical method for controlling and killing summer shoots of citru...
