Discuss Fertilizers Using Efficiency
& PINEYE® Emulsion User Guide.

Pesticide residue and using efficiency of fertilizers are the key discussion for farmers. A higher pesticide and fertilizer rate not only waste of money, customers also prefer to choose organic food.

Release control will reduce the rate of diffusion. Using PINEYE® Emulsion for an hour before the rain comes, the product is forming an elasticity film to slow down rain penetrates through cuticles. This application will prevent farmers re-spray the pesticides twice time after a rainy day.


Even customers prefer to choose organic food today, the pesticide residue is still an important issue in many regions. In China, the safety percentage of vegetables is 97.4% ( CMOA, 2011). According to the historical statistics that farmers sprayed pesticides once time per 10 days in April and increase sprayed per 5 or 7 days in the summer. And then slow down the spraying time to every 15 days in October. (Dong Qinli, 2009) The leaf vegetables often retain the highest rate of pesticide residue, because the leaves have large surface area and touch with pesticides directly.

A study was reported that 45% of farmers would consider the safety interval, 38% of farmers may consider the intervals, but 17% of farmers would not consider this issue. More than 55% of farmers said that the higher toxicity the better efficacy. (Tong Xia, 2014)

Re-spray pesticides are the main way on residue issue, such as on a rainy day, the rains can clean away the pesticides from the surface of foliage if farmer spraying before rainy they will spray again when the sun comes out.

In the performance test, the deposit rate of PINEYE® Emulsion is 6.6623 mg/cm2. When farmers sprayed pesticides mix with PINEYE® Emulsion, the piney resin polymer can increase the extended area of pesticide on the surface. After spraying for an hour, polymer emulsion goes dryness and forming an elasticity film. The film wraps up liquid in the microcapsule and defence water cleans away the pesticide or other addition agents directly.

The key ingredient of PINEYE® Emulsion is a biobased polymer, which is natural-friendly to crops, flowers, and fruits. Compared with other adjuvants,  it shows 44.50 degrees of contact angle in the test, the value is better than the organic-based competing product, who shows 55.48 degrees of contact angle. The lower angle contact means the better wetting function if you use PINEYE® Emulsion as the dispersant agent.


The soil is an ecosystem that PH meter was affected by the fertilizer using. An overdose rate using and the low using efficiency may destroy a healthy soil ecosystem. One of an important issue is soil acidification. For example on fertilizer N, only 28.3% of using efficiency for rice, 28.2% for wheat and 26.1% for maize. The rate of fertilizer N is 46 to 276 kg/ha for rice, 60 to 383 kg/ha for wheat and 37 to 360 kg/ha for maize. More than 70% fertilizer was absorbed by the soil. (Program 948, CMOA)

According to a study by Chinese Academy of Agricultural Sciences (CAAS), the PH meter of Chinese farming soil is a trend to acidification 1.0 to 1.5 unite among 19 to 24a sample during 24 years. (Meng Hongqi, 2012) Fertilizer N deposition can acidify the soil and leach the exchangeable base cations that field trend to barren.

Rice 396 46 to 276 25 to 235 19 to 155
Wheat 588 60 to 383 26 to 192 15 to 350
Maize 349 37 to 360 45 to 180 30 to 225

In many cases, you can easily using water dilute PINEYE® Emulsion and then mixing into pesticide formulas. We suggest you selecting bio-pesticide because bio-pesticide is naturally prepared from organic monomers, especially which active ingredients were extracted from terpenes based. The based blending ratio is 1:100 with water, the application will be changed when the ratio changed.

If you plan to use PINEYE™ Emulsion as wetting dispersant at your citrus grange, and the water using rate is 400L/ha.

350 (Reference from Table.3) * 170 ( Size of sprinkler, that is 170L sprinkler in the case) / 400 ( water using rate per ha) = 148.75ml


If you want to use emulsion as potentiator in same hypothetical condition.

600 (Reference from Table.3) * 170 ( Size of sprinkler, that is 170L sprinkler in the case) / 400 ( water using rate per ha) = 255ml
