In the time of after planting 70 days, control efficiency to aphid, wireworm, cutworm, grub and mole cricket is investigated, investigation method comprises: at same growing area, select at random 10 sample points, every 10 caves, amount to 20 caves, every cave shoveling 2kg, the degree of depth is to 30cm, borer population alive to wireworm, cutworm, grub and mole cricket is counted respectively, each growing area adopts random 5 samplings, every 4 strains, the aphid number on investigation wheat leaf blade, then according to formula (A), calculate pest control effect, result is as shown in table 2.
In the time of after planting 90 days, control efficiency to rust, smut, root rot and head blight is investigated, investigation method comprises: each growing area adopts random 10 samplings, each growing area is investigated 30 strains, investigate diseased plant rate and the disease index of each treatment region root rot in seedling stage, according to formula (B) and formula (C), calculate control efficiency.Wherein, root rot severity Scaling index: 0 grade: on stem foot and main fibrous root all without scab; 1 grade: on stem foot and main root, have a small amount of scab; 3 grades: on stem foot and main root, scab is more, lesion area accounts for the 1/4-1/2 of stem foot and the root gross area; 5 grades: on stem foot and main root, scab is many and large, and lesion area accounts for the 1/2-3/4 of stem foot and the root gross area; 7 grades: on stem foot and main root, scab in flakes, forms around neck phenomenon, but root system is not dead; 9 grades: root system is downright bad, plant overground part is wilted or is dead.Rust, smut and head blight state of an illness statistics are with reference to < < GB/T17980 pesticide field efficacy medicine test criterion > >, and the control efficiency of rust, smut and head blight is calculated according to formula (D).The results are shown in Table 2.
Table 2
Test implementation example 3
The composition pesticide of this TEST EXAMPLES Test Example 1-9 and comparative example 1-9 is the effect in integrated control paddy rice damage by disease and insect (small brown rice planthopper, aphid, leafhopper, rotten kind, damping off and bakanae disease) as seed coat agent.
Using the composition pesticide of embodiment 1-9 and comparative example 1-9 as seed coat agent respectively as seed coat agent, rice paddy seed is carried out to Cotton seeds (rice paddy seed of every 1kg is used 1.9g seed coat agent, during use, seed coat agent is added to be poured on after the dilution of equal-volume water to be stirred to all seeds on seed and all to catch equably the color of acid red).By the rice paddy seed that does not carry out Cotton seeds in contrast.
Seed after dressing is sowed to line-spacing 20cm, spacing in the rows 16.7cm.Soil, the cultivation of the growing area of different seed coat agents processing and control treatment are identical with water and fertilizer management condition.
In the time of after planting 90 days, small brown rice planthopper, aphid and leafhopper control efficiency are investigated, investigation method is carried out according to < < GB/T17980 pesticide field efficacy medicine test criterion > >, and calculate pest control effect according to formula (A), result is as shown in table 3.
In the time of after planting 70 days, control efficiency to rotten kind, damping off and bakanae disease is investigated, investigation method is carried out according to < < GB/T17980 pesticide field efficacy medicine test criterion > >, and calculates pest control effect according to formula (B) and formula (C).The results are shown in Table 3.
