Atrazine 90 WDG

Triazine herbicides are an important type of herbicides that play an important role in crop protection. SINVOCHEM synthesis and application R&D team has developed SP-WG77s. With narrow molecular weight distribution and controllable structure of hydrophilic and lipophilic chain segments, it is an excellent dispersant for high loading triazine water dispersible granules.

 Highly cost-effective, , 90% Atrazine WDG with excellent performance can be prepared by adding only 3%        dispersant SP-WG77 in formula.

 .

 .

 Good hard water resistance, fast disintegration in triple hard water, high suspensibility, suitable for different application scenarios.

Test 1: Laboratory Trial

We formulated 90% Atrazine WDG with dispersant SP-WG77 and three commercial dispersant 1#, 2#, 3#, wet sieve tests were carried out and the results are shown below.

Figure 1:Wet sieving test of 90% Atrazine WDG with different dispersants

Compared to commercial dispersants, 90% Atrazine WDG formulated with SP-WG77 shows higher pass rate in the wet sieve test (see figure 1). This indicates that with SP-WG77, we can use low use rate and still achieve good performance of the formulation.

Test 2: Performance test

Table 2:Test results of 90% Atrazine WDG commercial products and prepared with SP-WG77

It can be seen that formulation with SP-WG77 shows mist dispersion into water and disintegrates completely after 18 times of inversion. Besides, formulation with SP-WG77 demonstrates better resistance to stand triple hard water than commercially available formulations of 1#, 2# and 3#.
