Glyphosate is the most widely used pesticide compound in the world. According to statistics, the annual market share of glyphosate in the world reaches 8.8 billion dollars, and the consumption occupies the first place. In the words of farmers, the amount of glyphosate is similar to that of water.

In many places in China, the conventional dosage of glyphosate isopropylamine 41% is 150ml/15L water, and in some places it reaches 200ml/15L water, and the dosage for some weeds is even greater. With the continuous use of glyphosate and the increase of weed resistance level year by year, it not only increases the use cost of farmers, but also greatly reduces the income of glyphosate dealers.

In order to improve the application effect of glyphosate, reduce the cost of farmers and enhance the core competitiveness of operators, Oasis developed a adjuvant ——FirstWiner, which can effectively improve the utilization rate of glyphosate. It improves the effect of the product by adjusting the softness and hardness of the water and enhancing the spreadability of the compound, so as to achieve the purpose of reducing the dosage and increasing the effect.

The following shows the recent experimental results:

• On June 4 th, the target weed Solidago canadensis

1. Glyphosate 480g/L 100 times + Synergist 1000 times (Group A)

June 4th, the experiment started                     June 7th,the 3rd day after treatment

June 11th, the 7th day after treatment                     July 14th, the 40th day after treatment

2. Glyphosate 480g/L 150 times + Synergist 1000 times (Group B)

June 4th, the experiment started                             June 7th,the 3rd day after treatment

June 11th, the 7th day after treatment                        July 14th, the 40th day after treatment

3. Glyphosate 480g/L 100 times used alone (Group C)

June 4th, the experiment started        June 7th,the 3rd day after treatment

June 11th, the 7th day after treatment     July 14th, the 40th day after treatment

Comparing group A with group C, it can be concluded that the quick-acting effect and lasting period after adding synergist are stronger than those of group C, whether on the 3rd or 7th day after treatment.

Comparing group B with group C, the effects of the two groups are similar on the 3rd, 7th and 40th days after treatment, so the following conclusions can be drawn:

When glyphosate is 100 times, the effect after adding synergist is obviously better than that of using it alone. When glyphosate is 150 times, the effect after adding synergist is basically the same as that of glyphosate 100 times alone. Therefore, the synergist has an obvious effect of reducing dosage.

• Common gramineous weeds

1. Glyphosate 480g/L 100 times + Synergist 1000 times (Group D)

3 days after the experiment                               7 days after the experiment

2. Glyphosate 480g/L 150 times + Synergist 1000 times (Group E)

3 days after the experiment                                      7 days after the experiment

3. Glyphosate 480g/L 100 times used alone (Group F)

It can be seen from the three groups of DEF photos that the effect on gramineous weeds is basically the same, but the effect on individual perennial weeds is not significant, as shown in the following weeds:

Therefore, it can be concluded that for annual weeds, adding the adjuvant Rirstwiner can significantly improve the efficacy of the product and reduce the amount of glyphosate, thereby reducing the cost of use.
