Abstract
The invention belongs to the technical field of agricultural herbicides and particularly relates to pyrithiobac-sodium herbicide for hot pepper fields. The pyrithiobac-sodium herbicide comprises, by weight percent, 1-80% of pyrithiobac-sodium and 0.05-5% of safener. The safener is one or mixture of any of fulvic acid, brassinolide, urea, and monopotassium phosphate or monosodium phosphate buffer solution. The pyrithiobac-sodium herbicide solves the problem that tarditioanl pyrithiobac-sodium herbicide causes browning and malformation of seedlings of hot pepper and is evident in drug effect, low in cost and environment-friendly.

For herbicidal effect between the checking different dosage form with to the difference of the safety of capsicum, we test in the land for growing field crops.Embodiment 1:10% pyrithiobac-sodium aqua, embodiment 4:40% pyrithiobac-sodium soluble powder, embodiment 5:30% pyrithiobac-sodium water dispersible granules, same dose is to the preventive effect of capsicum field weed with to the safety of capsicum, and experimental result is seen table 1.Spray pesticide was done closed soil treatment before test was adopted and broadcast the back seedling, converted 40 kilograms of the water yields for every mu, and 40 days sampling survey weeds strain numbers behind the medicine detect the safety to capsicum.
40 days effects of the different preparations control of table 1 pyrithiobac-sodium capsicum field weed and safety
Can be found out that by table 1 the different dosage form medicament has good herbicidal effect to the capsicum field weed under same amount, overall preventive effect is all more than 96%.Each is handled capsicum safety, and plant height and fresh weight do not reach significance of difference level.
For verifying existing pyrithiobac-sodium weed killer herbicide that does not add safener and the herbicidal effect between the present invention and to the difference of the safety of capsicum, the applicant tests the preventive effect of capsicum field weed, concrete test situation and result are following:
Application method: spray pesticide is done closed soil treatment before broadcasting the back seedling, converts 40 kilograms/mu of the water yields.
The efficacy survey method: 40 days sampling survey weeds strain numbers behind the medicine, every sub-district is 3 point samplings at random, 0.2 square metre every (circle, radius are 0.25 meter), count 0.6 square metre in weeds kind, strain number, preventive effect is counted in the meter strain, the computing formula of preventive effect is following:
Plant height is measured in every sub-district and random sampling even capsicum seedling 25 strains of growing, and estimates the safety of medicament to crop.
Experimental data is as shown in table 2: in the table 2, Comparative Examples is not for adding 10% pyrithiobac-sodium aqua of safener.
Table 2 pyrithiobac-sodium is to the preventive effect of capsicum field weed
Find out that from table 2 supply each processing of reagent agent that control capsicum field weed is all had good herbicidal effect, overall preventive effect is all more than 95%, it is little that each medicament various dose is handled differences, all do not reach significance.
From test, can learn that pyrithiobac-sodium all has good herbicidal effect to grassy weed, broadleaved herb, the sedge weed cyperus iria is also had good preventive effect.Pernicious broad leaved weed dayflower, trailing plants Japonica grass there is the obvious suppression growth result.
Each chemicals treatment district capsicum, capsicum emerges normally behind the medicine, but the capsicum of Comparative Examples treatment region has symptom of chemical damage such as yellow, deformity after emerging.Behind the medicine 40 days through each sub-district sampling survey; Average plant height and fresh weight; The Comparative Examples treatment region reaches significance level with dispenser check plot not and embodiment 1 treatment region comparing difference, show supply the reagent agent to add safener after each dosage process range of pyrithiobac-sodium interior to capsicum safety.
