Embodiment 1

[0027] Preparation method of 90% diafenthiuron·nitenpyram wettable powder

[0028] Diafenthiuron 85kg

[0029] Nitenpyram 5kg

[0030] Pull open powder 3kg

[0031] Sodium Lauryl Sulfate 3kg

[0032] Kaolin make up to 100kg

[0033] The various ingredients are mixed together, and the product is obtained by jet milling and passing through a 325-mesh sieve. Pull open powder and sodium lauryl sulfate can effectively prevent and delay the decomposition of active ingredients or deterioration of physical properties of pesticide preparations during storage and transportation, and improve the effect of action.

Embodiment 2

[0035] Preparation method of 1% diafenthiuron·nitenpyram aqueous emulsion

[0036] Diafenthiuron 0.5kg

[0037] Nitenpyram 0.5kg

[0038] Isopropanol 10kg

[0039] Dimethylformamide 2kg

[0040] Xylene 5kg

[0041] Emulsifier 10kg

[0042] Water up to 100kg

[0043] Mix various ingredients together, and shear in a shearing kettle until the particle size of the active ingredient is less than 3 μm. The function of the emulsifier is that when it is dispersed on the surface of the dispersant, the formation of a thin film or electric double layer can make the dispersed phase charge, and prevent the small droplets of the dispersed phase from coagulating with each other. Isopropanol and xylene can effectively fuse emulsifiable concentrate with water and maintain its stability.

Embodiment 3

[0045] Preparation method of 35% diafenthiuron·nitenpyram emulsifiable concentrate

[0046] Diafenthiuron 25kg

[0047] Nitenpyram 10kg

[0048] Dimethylformamide 40kg

[0049] Emulsifier 603# 5kg

[0050]Emulsifier 500# 5kg

[0051] Xylene make up to 100kg

[0052] Combine ingredients until smooth, stirring until creamy.

Abstract

The invention provides a compounded pesticide preparation made from diafenthiuron and nitenpyram; the active ingredient content of the compounded preparation is 1 to 90 percent and the proportion of diafenthiuron and nitenpyram is 0.2-50:1. The compounded preparation can be processed into water dispersible granule, suspending agent, wettable powder, soluble liquid, aqueous emulsion or missible oil and the like, after being added with various excipients, addition agents and carriers. The invention can be used for killing a plurality of pests and has great applicability; the compounded preparation of diafenthiuron and nitenpyram has excellent preventative effect on aphid, plant hopper, thrips, leafhopper and the like, and has controlling effect on pests such as whitefly, diamond-back moth, red spider and the like. Moreover, the compounded pesticide preparation of the invention has comparatively quick and endurable action on pest killing and is characterized by low poison and residue, excellent security and low cost when in compounded use.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a compound pesticide composition containing diafenthiuron and nitenpyram, which is mainly used for killing insects on economic crops and rice. Background technique [0002] Pests that harm economic crops and rice are mainly divided into two categories, one of which is the pests with piercing and sucking mouthparts. The pests with piercing and sucking mouthparts mainly damage rice, fruit trees, vegetables and tea, aphids, planthoppers, thrips, leafhoppers and other pests. [0003] Aphids are one of the main pests that harm economic crops. The aphids that harm vegetables mainly include green peach aphid (Pipa aphid), radish aphid and melon aphid. All three aphids are worldwide pests with a wide range of distribution. It mainly damages young leaves, buds, flower buds and other young organs of plants. It penetrates plant tissues with piercing-sucking mouthparts and absorbs a large amount ...
