Embodiment 1

[0020] First introduce the following substances into a mixer, add them in order and stir and mix at room temperature and normal pressure:

[0021] Distilled water, industrial alcohol, monosultap (generally greater than 90%), NP-15, stirred and mixed under normal temperature and pressure until the system is uniform and transparent, slowly add triazophos crude oil (content greater than 80%), and continue to stir the system , the system gradually changed from turbid to uniform and transparent, and the composition was successfully prepared.

[0022] Distilled water 545.5g

[0023] Denatured alcohol 150g

[0024] Monosultap 112g

[0025] NP-15 130g

[0026] Triazophos crude oil 62.5g

Embodiment 2

[0028] In this example, the preparation steps are as described in Example 1, but the ratio of triazophos and monosultap is increased, and the amount of NP-15 is increased simultaneously, so that the physical and chemical properties of the product meet the standard requirements.

[0029] Distilled water 464g

[0030] Denatured alcohol 150g

[0031] Monosultap 112g

[0032] NP-15 180g

[0033] Triazophos crude oil 94g

Embodiment 3

[0035] In this example, the preparation steps described in example 1, while increasing the amount of NP-15, so that the physical and chemical properties of the product meet the standard requirements.

[0036] Distilled water 489g

[0037] Denatured alcohol 150g

[0038] Monosultap 56g

[0039] NP-15 180g

[0040] Triazophos crude oil 125g

Abstract

The plant protective composition comprises monosultap and triazophos in the weight ratio of 0.1-10, preferably 0.5-2. The micro emulsion consists of monosultap and triazophos as well as emulsifier, distilled water and alcohol. The micro emulsion as one environment protecting form as a preferential one is prepared by using water, rather than organic solvent, as solvent and has no environmental pollution caused by organic solvent and dust pollution. It has strong adhering force on crop, long effective period and powerful penetration to pest body.

Description

1. Technical field [0001] The invention relates to a plant protection composition for controlling rice stem borer and a preparation method thereof, especially a plant protection composition mainly composed of monosultap and triazophos and a process for preparing the composition. It is a new industrial product , especially for protecting rice from stem borers. 2. Background technology [0002] Among the three main food crops, rice has the largest planting area, and Jiangsu Province alone has more than 50 million mu of rice planted. In recent years, with the improvement of people's living standards, the requirements for rice quality have also increased, and many areas have implemented "indica to japonica". Japonica rice has a long growth period, a high probability of being damaged by pests, and its low insect resistance, which intensifies the occurrence of rice pests. The pests that occur all year round include rice stem borer, rice stem borer, leaf roller, and large borer, e...
